液压抽油机设计

液压抽油机设计 1 绪论 1.1 本课题来源及研究的目的和意义 随着原油储量日益减少, 开采难度的增大, 油田对新型采油方法以及采油设备的探索及 构思也在日益更新中。抽油机作为一种普及的采油设备,也在不断的构思和日益更新中。液 压抽油机作为近些年来迅猛发展的新型抽油设备,有着优于传统设备的强项。 增大载荷是本课题研究的目的之一, 是在结构最简, 材料最省得方案下尽可能的增大其 工作载荷。传统的游梁抽油机虽有大载荷的特点,但这种旧型设备体型笨重,运输和安装都 较为麻烦,尤其是海上平台更是不允许过的的大质量设备。能在质量最轻和结构最简的情况 下增大工作载荷,有着方便运输以及满足海上平台开采要求的重要意义。 节能减排是本课题研究的目的之二。到 1995 年统计的游梁抽油机总数约为 4 万台,但 使用期却没有超过 5年的, 如果每年需更换10%的设备, 使用的钢材金额会在 1.5 亿元左右。 首先不看使用寿命,这种旧型设备本省的钢材用量就非常的大。液压抽油机工作原理不是曲 柄连杆机构或者其变形,工作原理在本身结构上的改进就省去了大量的钢材,有着改善采油 设备经济性的重要意义。 此外结构上的优化方便了安装, 同时也方便了拆卸和运输, 即故障诊断更换坏损元件也 相对方便了许多。在工作上迅速的故障诊断与维修有着增加设备连续工作时间的意义。 1.2 本课题所涉及的问题在国内的研究现状及分析 我国开始研究液压抽油机是从60 年代开始的。 1966 年北京石油学院提出“液压泵—液压缸”结构的抽油机,以液压缸伸缩来完成主 要工作,同时用油管做平衡重,并利用其往复运动增大冲程。 1987 年吉林工业大学研制出YCJ-II型液压抽油机,同样以液压缸做驱动。 1992 年、1993年兰州石油机械研究所、浙江大学先后以“液压泵—液压马达”结构研 制出新型液压抽油机。此后至近几年来,随着油田开采的要求, 液压技术、密封技术的发展, 液压元件的成熟,液压抽油机业迅速发展起来。 以下对上述几种抽油机作简要分析: YCJ—II型液压抽油机直接用液压缸的直线往复运动工作,具有结构简单,比常规抽油 机节能的特点。在辽河油田的实验说明其在北方冬季野外有可连续运行的能力,其液压与电 气系统亦是可行的。不足在于:安全保护措施有所欠缺,对机电一体化技术应用不足等。 YCJ12—12—2500 型滚筒式液压抽油机利用换向阀控制液压马达的正反转,以齿轮— 齿条机构实现往复运动, 同时采用了机械平衡方式。 在液压系统上弥补了YCJ—II型的不足, 同时整机平稳运行。 功率回收型液压抽油机利用了“变量泵—马达”这一特殊元件,实现了“长冲程,低冲 次,大载荷”的特点,并有安全保护功能。最重要的是它通过能量的储存于转换使功率回收, 而且相当完全,平衡也是最完美的。 1.3 本课题所涉及的问题在国外的研究现状及分析 国外对于液压抽油机的研制起步较早,但由于翻译过的外文文献较少,这里只做介绍, 不做详细分析。 1961 年美国 Axelson 公司研制出 Hydrox 长冲程 CB 型液压抽油机,冲程 1.2~7.95m, 适井深度 670~2032m,并在几个大油田获得成功的应用性实验。 1965 年苏联研制出 ArH 油管平衡式液压抽油机,可分开调节上下冲程的速度,冲程长 度 1.625~4.275m。目前,这类产品已形成产品系列。1977 年加拿大研制出HEP 型液压抽油 机。冲程 10m,最高冲次 5.0/min,悬点载荷 34.23~195.64KN。

常用抽油机知识介绍

辽河油田常用抽油机知识介绍 第一节抽油机基础知识 1.1 概述 当地层具有的能量不足以将原油提升到地面时,就需要通过能量的转换来达到目的。有杆抽油设备(抽油机-抽油泵装置)因结构简单、制造容易、使用方便而成为目前应用最广泛的能量转换装置。 有杆抽油设备主要由三部分组成,一是地面部分;二是井下部分;三是联系地面和井下的中间部分。它是由地面部分(机械)将运动和动力进行转换后,通过中间部分(杆柱或管柱)传递给井下部分(泵),再通过井下部分(泵)将能量传递给原油,完成将原油提升到地面的任务。 游梁式抽油机因具有适应野外无人看管、全天候运转的条件和使用可靠等特点,从抽油机发展的开始到现在,它都是应用最广泛的抽油机。但随着井深和产量的不断增加,需要抽油机的能力就越大,游梁式抽油机重量大的缺点就越明显。为了减轻抽油机的重量,提升节能效果,近二十年来也大力推广应用了一些无游梁式抽油机。 1.2 抽油机的原理、结构、特点、分类及应用 按照抽油机结构和原理的不同,抽油机可分为游梁式抽油机和无游梁式抽油机。 一、游梁式抽油机 游梁式抽油机的基本特点是结构简单,制造容易,使用方便,特别是它可以长期在油田全天候运转,使用可靠。因此,尽管它存在驴头悬点运动的加速度较大、平衡效果较差、效率较低、在长冲程时体积较大和笨重等缺点,但仍然是目前应用最广泛的抽油机。 游梁式抽油机的工作 原理是:由动力机供给动力, 经减速器将动力机的高速转 动变为抽油机曲柄的低速转 动,并由曲柄—连杆—游梁 机构将旋转运动变为抽油机 驴头的上、下往复运动,经 悬绳器总成带动深井泵工 作。 游梁式抽油机的主要 部件有:提供动力的动力机; 传递动力并降低速度的减速 器;传递动力并将旋转运动 变成往复运动的四杆机构 (曲柄、连杆、游梁、支架及横梁和底座);传递动力并保证光杆做往复直线运动的驴头及悬绳器总成;使抽油机能停留在任意位置的刹车装置以及为使动力机能在一个较小的负载变化范围内工作的平衡装置等。 游梁式抽油机根据结构型式不同可分为:

外文翻译 英文原文 Belt Conveying Systems Development of driving system Among the methods of material conveying employed,belt conveyors play a very important part in the reliable carrying of material over long distances at competitive cost.Conveyor systems have become larger and more complex and drive systems have also been going through a process of evolution and will continue to do so.Nowadays,bigger belts require more power and have brought the need for larger individual drives as well as multiple drives such as 3 drives of 750 kW for one belt(this is the case for the conveyor drives in Chengzhuang Mine).The ability to control drive acceleration torque is critical to belt conveyors’performance.An efficient drive system should be able to provide smooth,soft starts while maintaining belt tensions within the specified safe limits.For load sharing on multiple drives.torque and speed control are also important considerations in the drive system’s design. Due to the advances in conveyor drive control technology,at present many more reliable.Cost-effective and performance-driven conveyor drive systems covering a wide range of power are available for customers’ choices[1]. 1 Analysis on conveyor drive technologies 1.1 Direct drives Full-voltage starters.With a full-voltage starter design,the conveyor head shaft is direct-coupled to the motor through the gear drive.Direct full-voltage starters are adequate for relatively low-power, simple-profile conveyors.With direct fu11-voltage starters.no control is provided for various conveyor loads and.depending on the ratio between fu11-and no-1oad power requirements,empty starting times can be three or four times faster than full load.The maintenance-free starting system is simple,low-cost and very reliable.However, they cannot control starting torque and maximum stall torque;therefore.they are

液压抽油机介绍

液压抽油机介绍 一、前言 随着定向井、海陆丛式井和水平井钻井技术的快速推进,现有采油设备已渐渐难以适应时代的发展,因此,液力无杆采油技术逐渐得到重视,早年的水力活塞泵虽因结构复杂而退出市场,但不能因此否定此种原理的可行性,无杆泵的设计成功,正是这种液力采油技术的一种延续、一种更新,它使我们在深井和超深井内采收稠油、高凝油有了可靠的保证。 二、技术特点 1,无杆泵是用标准抽油泵的零部件装配而成,所以,其使用寿命和工作环境与普通管式泵等同。 2,举升液活塞与动力液活塞的面积比可随意调节,从而使地面泵的输出压力随意降低。3,无杆泵是一种集加热和采油为一体的采油工具,工作时可将液压泵内原油加热后输送至无杆泵,这样,可将井下的稠油、蜡油热释降粘后举升到地面,在循环的全过程可保持温度均衡,可实现全井段降粘清蜡。 4,无杆泵动力液为油井采出液,即井内原油。 5,使用无杆泵后,没有机械传动部分,所以,运行效率高,节能节电。 三、工作原理 上冲程时,换向阀控制上油腔室的进油孔开启,出油孔关闭,同时控制下油腔室的进油孔关闭,出油孔开启,此时动力液经油管进入上油腔室推动柱塞管上行,使柱塞管上部原油、顶部油腔室内原油和下油腔室内原油流入油套环空,部分原油经油套环空被推向地面,与此同时,底部油腔室内将吸入部分原油,其目的是在降低推油压力的前提下,为下一个冲程做准备(见附图1)。 下冲程:当柱塞管上冲程至上止点时,换向阀自动将上油腔室的进油孔关闭,出油孔开启,并同时控制下油腔室的进油孔开启,出油孔关闭,这时动力液便进入下油腔室推动柱塞管下行,使柱塞管上部空间压力降低,从而,吸进井内原油,与此同时,底部油腔室和上油腔室内原油流入油套环空,部分原油经油套环空被推向地面,此时顶部油腔室吸入部分原油,以降低推油压力(见附图2),完成一个循环过程。全部抽油过程见动画示意图。 四、主要技术指标 项目指标 无杆泵总长4900mm 无杆泵两端扣型 2 1/2″TBG 泵体最大外径:112mm 双向作功冲程1400mm 动力液活塞直径Φ68mm×Φ68mm 举液活塞直径Φ38mm×Φ38mm 活塞作用面积比1:0.3 举液活塞总重量30Kg 无杆泵井下工作时间与管式泵等同 五、最小启动压力计算示例: 以泵挂深度2000米为例,油压1Mpa,不考虑泵沉没压力,举液活塞上行时,受力为:Φ38柱塞面上的液柱载荷2268.23 Kg,油压产生的压力113.4 Kg,泵筒与活塞的半干摩擦力0.35Kg (参考资料:泵径小于Φ70mm时,单个活塞摩擦力小于1.717N),活塞自重30Kg,动力液水力损失258.6Kg(动力液水力损失每千米1.14 Mpa),合计2670.58 Kg

第一章:应力与应变 1.That branch of scientific analysis which motions, times and forces is called mechanics and is made up of two parts, statics and dynamics. 研究位移、时间和力运动乘力是科学分析法的一个分歧,被称作力学,力学由两大部分组成,静力学和动力学。 2.For example, if the force operating on a sleeve bearing becomes too high, it will squeeze out the oil film and cause metal-to-metal contact, overheating and rapid failure of the bearing. 例如:如果止推轴承上的作用力过大的话,会挤出油膜,引起金属和金属之间的相互接触,轴承将过热而迅速失效。 3.Our intuitive concept of force includes such ideas as place of application, direction, and magnitude, and these are called the characteristics of a force. 力的直观概念包括力的作用点、大小、方向,这些被称为力的三要素。 4.All bodies are either elastic or plastic and will be deformed if acted upon by forces. When the deformation of such bodies is small, they are frequently assumed to be rigid, i.e., incapable of deformation, in order to simplify the analysis. 所有的物体既可以是弹性的也可以是塑性的,如果受到力的作用就产生变形。当变形很小的时候它们被假设成刚体,也就是不产生变形。 5.The rigid-body assumption cannot be used in internal stresses and strains due to the applied forces to be analyzed.
