石油化学化工专业英语第六单元翻译
Professional English for Chemical Engineering(化工专业英语)---6
根据学科领域确定词义
同一个词在不同领域表示不同的含义，这 是因为各行各业都尽量采用常用词汇来表 达各自专业的概念。
The lathe should be set on a firm base 车床应该安装在坚实的底座上。 As we all know, a base reacts with an acid to form a salt 众所周知，碱与酸反应生成盐。 A transistor has three electrodes, the emitter, the base and the collector. 晶体管有三个电极，即发射极、基极和集电极 Line AB is the base of the triangle ABC AB线是三角形ABC的底边 Mathematics is the base of all other science 数学是所有其他科学的基础。
词类引申
因为普通词汇在专业英语中往往具有专业含义， 因此，在翻译时需要体现出相应的引申意义。 Whichever way the two two-way switches are left, one of the wires is alive and the other is dead 无论这两个双路开关合在那一边，两个导线中总 有一根式带电的，一根是不带电的。 Such a ring of feed flow is called internal loop reactor 这样的一个原料物流的环路流动就被叫做内循环 反应器。
根据词类确定词义
英语中有些词在不同的句子中属于不同的 词类，词类不同，其词义不同。 例如: Back: 作副词为“回来”；动词为 “支持”，形容词为“过期的”，名词指 “背面”、“背部”等。 因此，对于这类词汇，翻译时应该首先判 明其词性，再进一步确定词义

06．THE CLASSIFICATION OF INORGANIC COMPOUNDS The Classes of Compounds该类化合物Thousands and tens of thousands of compounds are known to the chemist today. It would be impossible to learn properties and behavior of even a fraction of this number if it had to be done on the basis of individual compounds1. Fortunately, most chemical compounds can be grouped together in a few classes. Then, if we can properly classify a compound .we are at once aware of the general properties of the compound from knowledge of the properties of that class or group of compounds. For example. HCl is classed as an acid. and by becoming familiar with the behavior of acids as a distinct class, we are at once aware of the general properties of the compound2. A great many of the compounds we are to study may be classified as acids, bases, salts, metallic oxides, or nonmetallic oxides. Of these five classes of compounds, the first three —acids, bases, and salts — are by far the most important3…成千上万的化合物是众所周知的今天的化学家。

石油工程专业英语(汉译英)
UNIT 1The petroleum industry plays a decisive role in the modern industry,and also plays a very important role on the social, economic development.Petroleum includes crude oil and natural gas in a broad sense, but it refers only to crude oil in a narrow sense.In China, the oil industry is divided into upstream (oil exploration, exploitation ,storage and transportation) and downstream (petroleum processing and sales) .While in a foreign country, this industry is divided into upstream sector, midstream sector and downstream sector,oil storage and transportation industry is in the midstream sector.In petroleum exploration, geologist, seismologist, geophysics and geochemists find oil containing structure (TRAP)through rock analysis, seismic exploration and satellite remote sensing method to , and then confirm whether the structure contains the petroleum with industrial exploitation value through the drilling.Once the industrial oil flow appears, the structure can be put into development. In the development of petroleum, Petroleum Engineers (including drilling, oil extraction, oil, transportation engineers) in a variety of modern petroleum exploration technology, as much as possible from underground mining oil.In the early development of the oil reservoirs, can rely on its own energy from the ground.When the formation energy is exhausted, the artificial water flooding, gas injection, pumping and other methods to maintain a certain output, in the mining period, usually use some method of enhanced oil recovery to increase oil production and ultimate recoveryPetroleum processing can be divided into roughing and fine machining.In general, the upstream oil industry coarse processing (such as crude oil dehydration, degassing, and sand, natural gas dehydration and desulfurization), and fine processing of refinery completed by.In refinery, oil is refined into available commodity (such as gasoline, diesel, paraffin, asphalt) and industria l raw materials.UNIT 2Petroleum is hydrocarbon found in underground rock. In general, the oil was formed by biological bodies over millions of years under hypoxic ,high pressure and high temperature conditions. .But someothers think that petroleum was formed by acetylene that came from the hydrolyzed calcium carbide under high temperature, high pressure conditions.The oil migrated to a closed trap from the oil source over a long period of time,which is the reservoir what people mon traps have anticline trap, salt dome trap, coral reef trap and fault trap.three elements are eccensial:the Reservoir that accumulates petroleum,the barriert that prevent petrolum from escaping,the source that foms petroleum.Reservoir fluid including oil, gas, water.If the reservoir pressure is less than the saturation pressure of crude oil, the ma cro due to gravity difference in oil, gas and water: reservoir upper is gas, central is the crude oil, the lower is the water; at the micro level, if the reservoir is water wet, water distribution in the pore surface, oil distribution in pore CentralUNIT 3Oil is a natural mixtures that consists mainly of hydrocarbon.Petroleum includes crude oil and natural gas in a broad sense, but it refers only to crude oil in a narrow sense. Hydrocarbons is the main component of petroleum.According to the chemical composition,oil can be divided into alkanes, cycloalkanes, aromatic hydrocarbon.According to the relative density,oil can be divided into light and heavy oil.Oil in the hydrocarbon material, there are some non-hydrocarbon, mainly oxygen containing co mpounds (such as acids, esters, ketones, alcohols, phenols and), nitrogen (such as amide, pyridine, indoles and pyrroles etc.), sulphur compounds and non hydrocarbon material (such as carbon dioxide, nitrogen and hydrogen sulfide).Natural gas by methane content is divided into dry gas and moisture.Dry gas is methane content of more than 98% of the natural gas, the moisture is rich in ethane, propane and butane gas.Liquefied petroleum gas mainly containing ethane, propane and butane.Natural gas non hydrocarbon gases are mainly nitrogen, helium, carbon dioxide and hydrogen sulfide.UNIT 4Petroleum and natural gas is stored in the cracks and pores of rock,rather than buried in the underground oil pool or oil river.Whether a petroleum reservoir has the industry value of mining or not depends on its rock properties,that is the reservoir rock must have a certain degree of reservoir and permeability.Porosity is the main parameter of rock reservoir, permeability is the main parameters of rock permeability.The reservoir usually contain oil, gas and water three-phase flow.Description of multiphase fluid flow parameter is relative easy degree of relative permeability.Relative permeability is defined as the effective permeability of a fluid rock absolute perme ability ratio.In reservoir exploitation process, the fluid phase relative permeability with different phases in the reservoir fluid s aturation changes, at the beginning of exploitation, high oil saturation, oil phase relative permeability is bigger, oil is more; in late stage of production, high water saturation, water phase relative permeability is bigger, more water production.Capillary pressure curve can describe the reservoir rock pore size distribution and reservoir rock microscopic inhomogeneity.If the reservoir rock pore distribution, reservoir ultimate recovery rate is higher.UNIT 5Drilling is the important part of petroleum engineering.Oil field exploration period need to make exploration and evaluation well, at the initial stage of development need to well, later need to make encryption by.Drilling equipment used for drilling rig, drilling machine is mainly composed of a power system, rotating system, a lifting s ystem and mud circulating system.The power system comprises a large diesel engine and d iesel generator; rotary system consists of a water faucet, drill pipe, drill, drill pipe and drill plate and other components; lifting system consists of winch, wire rope, pulley components; mud circulating system by a mud pump, vibration sieve, mud, mud, mud tank gas separation system.Well prepared to drilling.Began drilling surface hole, casing and cementing; the next is drilled by a drill drive, Kelly, a d rill rod and a drill bit rotation.Bit cutting rock, while circulating mud cuttings out of the gro und.When the drill to a certain depth, in order to protect the shallow water is not polluted and prevent the formation of collapse, in turn into the surface casing, intermediat e casing, casing, and fixed with cement; finally through the perforation or other open oil well completion method.Install oil tree, test well productivity, finally will be delivered to the oil well production unit.UNIT 6In general, a well has multiple casing strings, in proper sequence, from top to bottom that is the conductor pipe ,surface casing, intermediate casing, production casing.The space between the casing and the formation or among the casings are needed to be fixed with cement.The main function of casing is to fix the wall and prevent it from falling in.The completion operation is needed when the drill bit through the pletion work includes casing, perforation (or other well completion method) and oil testingWell completion method includes open hole completion, perforation completion, wire-wrapped screen pipe completion, tubingless completion and multiple completion.Open hole completion refers only to the top of the reservoir casing, formation open well completion method.The method is applicable to limestone, dolomite reservoir; perforated completion is the most widely used well completion method.Perforating gun for the casing wall, cement sheath and formation open, guide the oil from the oil reservoir into the well, the method is suitable for most sandstone reservoir; for loose sandstone reservoir, can be use d in combination with wire wrapped screen gravel pack completion method, is used to prevent the production of oil Ide Sa.For s mall size hole, can be used without tubing completion.UNIT 7Oil recovery is one of the most important part of petroleum engineering,with its mission is to mining underground crude oil as much as possible.In general, at an early stage of development, the flow of oil can spout out to the surface relying on its own energy.But the reservoir itself energy depletes quickly, oil recovery must rely on artificial lift technology.Artificial lift technology including gas lift, sucker rod pump and a rodless pump method.Gas lift is ground through the compr essor gas pumped downhole, the injected gas lift crude oil from flowing to the ground.Gas lift is suitable for offshore and inclined shaft of oil production.Sucker rod pump lifting (also called pumping unit or "pumps" oil) is the most widely used methods of extractio n, global oil production proportion exceeds 85%.A sucker rod pump for produ ction of single well in s mall, vertical well extraction.Rodless pump includes a hydraulic piston pump, hydraulic jet pump, screw pump and electric submersible pump.Hydraulic piston pump for deep well, horizontal well, well, sand and high wax content well; hydraulic jet pump for deep well with high temperature, sand, corrosive medium and thick oil well adaptability; screw pump for viscous oil recovery; electric submersible pump is suitable for high yield oil wells and offshore oil.UNIT 8In general, from the oil well output is not a single phase fluid, product in the gas phase, liquid phase and solid phase.The gas phase are natural gas, carbon dioxide, hydrogen sulfide, nitrogen; liquid phase oil and water; solid phase of fine sand, silt and asphalt.Therefore, oil production of middle product separation and processing is a very important link.The output of oil wells ground separation is the use of oil, gas, water density, using horizontal or vertical multiphase sepa rator of oil, gas, water separation.After the separation of oil still exist a certain amount of water and sulfur, cannot achieve the refinery crude oil index, so the need for further dewatering and desulfurization process.The use of advanced technology and centrifugal separation technology to treat the demulsification of crude oil can enter the refineries for refining and processing.Preliminary treatment of natural gas needs further processing to enter the commercial gas pipeline.Natural gas containing hydrogen sulphide must first be desulfurization absorption tower, and molecular sieve technology processing of natural gas can reach the required content indicators.In addition to natural gas containing methane, also contains a higher value of ethane, propane, b utane, liquefied petroleum gas.Through the rich gas recovery device to ethane, propane, natural gas is separated from the.Oilfield produced water must be treated to achieve water quality ually in produced water containing high salinity salts.Output after precipitation, filtration, sterilization, demulsification, remove water droplets and solid phase, microorganism, meet the injection water quality after reinjection formation, in order to maintain formation pressure.If the treated water is disc harged directly, must meet strict emission standard of national qualityUNIT 9Well testing is a reservoir engineer understanding of reservoir, to obtain an important means of reservoir parameters.Through the test can determine whether the received damage reservoir, reservoir whether faults exis t or not; identify the fault location; detection of reservoir boundaries; calculation of reservoir parameters such as permeability, flow, flow coefficient, transmission rate.Test classification is more complex, in accordance with the test well types can be divided into oil well and gas well testing; in accordance with the test point position can be divided into the ground and underground well testing well testing; according t o the test object can be classified as temperature, pressure, flow rate test; according to the flowing state of the fluid can be divided into stable and unstable well testing; according to the change of pressure direction can be divided into pressure buildup and pressure fa ll off test. UNIT 10Reservoir development process similar to the one of the ups and downs of life.When the reservoir development to a certain period, oil wells or water injection wells or less there will be some problems, just like human life that occur in a wide variety of diseases.Petroleum Engineer's main task is to as the doctor carry on the analysis and the diagnosis, and proposed solutions to the problem, to maintain the normal production of oil well.Oil well problems surface phenomenon is crude oil production decline, output increased water, sand, stop the pump, injection volume decreased and water pressure drop.Deep time may be due to the reservoir pressure drops, the reservoir inhomogeneity of oil increases, hurt, injection water quality variation of oil wells, mechanical failure, well cement ring, casing, pipe leakage.Petroleum engineer must be integrated multidisciplinary knowledge, using various means of diagnosis technology research and analysis, t o judge the real reason, propose the corresponding solution, so as to solve the problems.UNIT 11Reservoir development and cannot be produced all underground crude oil.Generally speaking, its energy can only be produced by the formation of underground oil 10% the left and right sides, even if the water flooding development can only be produced 30%~50% underground crude oil.That is to say, the reservoir development always are part of crude oil in the ground.The recovery rate is defined as the cumulative oil recovery percentage accounted for the underground crude oil reserves.In the process of oil production, people always try to as far as possible to improve oil recovery.IOR is defined as: in addition to its energy and water injection and formation, gas injection to maintain the reservoir pressure, any method can increase the crude oil recovery method, referred to as ERO.ERO include gas miscible flooding, chemical flooding, heat recovery, flooding and other microorganis ms; generalized ERO also includes infill drilling, horizontal well, fracturing and acidizing, water plugging and profile control.ERO is a comprehensive technology, involve geological, chemical, mechanical, oil, oil reservoir, computer science, need various disciplines, departments jointly, solidarity and cooperation, fully embody the industrial team spirit.UNIT 12Reservoir numerical simulation is an important means of modern reservoir development.A reservoir can only be developed once, and reservoir numerical simulation development can be achieved N "reservoir", that is through the establishment of numerical rese rvoir model, reservoir simulator, a reservoir "development" N.And the optimal development scheme is applied to the actual reservoir, thereby obtaining the highest recovery rate and the maximum economic benefit.Reservoir numerical simulation is based on the establishment of numerical reservoir model.By analyzing the reservoir geological characteristics, the collection of a large number of reservoir static and dynamic data, establish the primary reservoir model, and through the historical fitting, the correction for a more realistic model of reservoir.Reservoir numerical simulation is the key to establish a mathematical model of fluid flow in reservoir.Depending on the mater ial balance principle, the equation of state, heat and mass transfer equations, establish containing multiple pa rameter equations, through the establishment of finite difference mathematical methods in computer on reservoir numerical simulation.The whole process is called reservoir numerical simulator establishment.The present reservoir numerical simulation the main gas reservoir model, black oil model and component model.UNIT 13Oilfield development requires not only technically feasible, also called economically feasible, so the reservoir development program must contain economic evaluation.Economic assessment refers to the resources, engineering, technology and market evaluation based on Calculation of reservoir development, input, output and economic indexes, analyzing the uncertain factors of product ion, optimum scheme is recommended.Economic evaluation is the basic procedure: first collect production data (including drilling, oil recovery, oil reservoir, surface construction engineering data) and country, enterprise economic data (such as tax rate, interest rate, tax of profit of indus try of rate); and then calculating the financial indexes, such as net present value, internal rate of return, return on investment, the investment recovery period; finally the system risk analysis, put forward the optimum development plan.。

Part 2 Unit 4. 含氧化合物
问题
你知道多少种含氧化合物?
乙醇与乙醚之间的区别在哪?
你知道石油中最常见的含氧化合物是什么吗?
1.醇
在化学中醇是任意一种羟基(-OH)与烷基或取代烷基相连的有机化合物。
简单的链醇类的通式为CnH2n+1OH.
一般而言, 醇这个词是指乙醇
乙醇是一种无色、易挥发的液体, 有特殊香味, 可以通过蔗糖发酵制得。
工业上, 常用乙烯水合来生产乙醇——乙烯水合反应需要磷酸来催化。
乙醇是目前世界上应用最广泛的镇静剂, 已有几千年的历史了。
在IUPAC系统命名法中, 烷烃链的名称去掉最后的“e”, 再加上“ol”就变成了醇, 例如:“甲醇”和“乙醇”。
必要时, 羟基的位置要在烷烃名和醇”ol”之间标识出来: CH3CH2CH2OH为1-丙醇(propan-1-ol), CH3CHOHCH3为2-丙醇(propan-2-ol)。
有时, 这个位次数要写在系统名之前, 如1-propanol为1-丙醇而2-propanol 为2-丙醇.
如果存在一个更优官能团(如醛、酮类、羧酸), 则有必要采用前缀羟基”hydroxyl”来表示,例如: 1-hydroxyl-2-propanone(CH3COCH2OH)即1-羟基-2-丙醇。
醇的通用名常采用相应的烷基基团加上醇字, 如甲醇、乙醇、叔丁醇。
丙醇可以为正丙醇n-propyl或异丙醇, 主要取决于羟基与丙烷碳链上第一或第二个碳原子相连接。
异丙烷常常也称为仲丙醇.
醇有三种主要的结构: 伯(1°), 仲(2°)、叔(3°), 这是根据C-OH基团的碳原子与几个碳原子相连。
醇的常见名称中要在烷基前缀中标明级别。
例如(CH3)3COH是三级醇,俗称叔丁醇。
它也可以根据系统命名法原则命名为2-methylpropan-2-ol(2-甲基-2-丙醇)或2-methyl-2-propanol(2-甲基-2-丙醇), 一个丙烷链上在中间碳(#2)原子上连接有一个甲基和羟基。
乙醇是一种简单的“伯”醇。
最简单的仲醇是异丙醇(propan-2-ol), 一个简单的叔醇是叔丁醇(2-methylpropan-2-ol)。
2.醚
醚是一种包含一个醚基团的有机化合物, 其官能团是一个与两个(取代)烷基或芳基相连的氧原子. 其通式为R-O-R。
一个典型的例子就是二乙基醚, 通常最简单的如乙醚(二乙醚, CH3-CH2-O-CH2-CH3)。
在IUPAC系统命名法中, 醚的命名一般采用通式“alkoxyalkane—烷氧基烷”, 例如CH3-CH2-O-CH3是甲氧基乙烷methoxyethane。
如果醚的一部分是一个更为复杂的分子, 它可以表示为一个烷氧基取代物, 所以-OCH3可以当成“甲氧基-”基团。
简单的烷基要写在前面, 所以CH3-CH2-O-CH3应该写成甲氧基(CH3O)乙烷(CH2CH3)。
对于上述例子常见方法是采用加上”醚”的形式来定义两种烷基的名称, 如乙基甲基醚。
术语“伯醚”、“仲醚”和“叔醚”是指与醚氧相连的碳原子的级数。
在伯醚中只有这个碳原子只连接了一个碳原子, 如:CH3-CH2-O-CH2-CH3二乙醚。
仲醚的一个例子是二异丙基醚(CH3)2CH-O-CH(CH3)2; 叔醚如二叔丁基醚(CH3)3C-O-C (CH3)3 di-tert-butyl。
3.醛
醛是一种包含一个端位羰基的有机化合物。
这个官能团是由一个碳原子与氢原子相连, 同时又以双键形式连接到一个氧原子形成的基团(化学式O = CH -), 称为醛基。
醛基也称甲酰基formyl或methanoyl。
根据IUPAC系统命名法规定醛的命名为:
脂肪醛视为含有醛基在内的最长碳链的衍生物。
因此, 甲醛以甲烷的衍生物来得名, CH3CH2CH2CHO则为丁烷的衍生物丁醛。
只需把母体烷烃的后缀“-e烷”改为“-al醛”即可, 因而, HCHO就是甲醛; 而CH3CH2CH2CHO命名为丁醛。
在其他情况下,比如当一个-CHO基与一个碳环相连, 可以加后缀-carbaldehyde表示碳醛。
因此, C6H11CHO 称之为环己基甲醛cyclohexanecarbaldehyde。
如果存在另一个官能团, 则要用一个后缀, 醛基的名称以前缀甲酰基formyl –来命名。
这个前缀methanoyl尤佳。
如果这种化合物是一种天然产品或羧酸, 采用前缀oxo——“氧代”来表示碳原子是醛基的一部分; 例如,CHOCH2COOH命名3-oxopropanoic羧酸(3-氧代丙酸)。
4.酮
酮是一种包含一个羰基(C=O) 的化合物, 羰基与另外两个碳原子以R1(CO)R2的形式相连。
R2和R1的取代基团不能是氢(H)。
一个羰基碳与两个碳原子相连使酮与其他含氧化合物醛, 羧酸, 酯等区别开来。
羰基的双键也使酮与醇区分开来。
最简单的酮是丙酮、CH3-CO-CH3名叫propanone丙酮(系统命名)。
一般来说, 用IUPAC系统命名法命名酮只需改变母体烷烃后缀“-e烷”为“-one
酮”即可。
对于一般的酮, 主要采用一些传统名称, 如丙酮和二苯甲酮往往占主导地位, 这些名称可以认为是延续了IUPAC的系统名称, 尽管有些介绍性的化学教科书也常常使用像propanone丙基酮这样的名称。
Oxo”氧代”是酮官能团在IUPAC系统命名法的正式名称。
然而, 其他的前缀也常常在各种书籍和期刊中出现。
对于一些常见的化学物质(主要是在生物化学中), keto”酮的”或oxo”氧代”这些术语也常用来描述酮官能团。
5.羧酸
羧酸是存在一个羧基的有机酸, 其表达式为-C(=O)OH, 通常用-COOH或-CO2H表示。
羧酸是Bronsted-Lowry酸——它们是质子贡献者。
在IUPAC命名中, 羧酸加一个-oic的后缀, 即酸(例如, octanoic酸---辛酸)
在普通术语中, 后缀常用-ic表示酸(例如, 硬脂酸)。
羧基的碳一般在原有化合物中排在第一位, 因而没有必要给它编号。
如果羧酸含有碳碳双键, 则中缀要从”-an-烷”变为”-en-烯”来表示双键的存在
简单烯烃化合物中双键的位置要用数字标识出。
在IUPAC系统命名中, 羧酸优先于其他大多数官能团, 包括羟基和醛、酮的羰基。
羧酸是极性化合物, 相互间易形成氢键作用。
在高温下, 气相中羧酸通常是双分子缔和形式存在。
较小的羧酸(碳数为1 –5时), 可以与水互溶, 而对于大分子羧酸则溶解度很小, 这是因为烃基链逐渐最长造成的疏水作用增强。
羧酸更容易溶于非极性溶剂, 如醚类和醇类。
羧酸普遍存在于自然界中, 是典型的弱酸, 也就是说, 他们只能在水溶液中部分解离成H +阳离子和RCOO−阴离子。
例如, 在室温条件下, 只有0.02 %的醋酸分子解离在水里。
由于羧酸是弱酸, 在水溶液中, 下列形式的物质存在一个平衡关系。
