页岩气时频电磁法勘探研究*文/张春贺1 刘雪军2 何兰芳2 赵 国2 周印明2 朱永山2 (1 中国地质调查局油气资源调查中心,北京 100029;2 中国石油集团东方地球物理勘探有限责任公司,河北 涿州 072751)摘 要:本文介绍了在研究和总结含气页岩密度、极化率、电阻率等岩石物理特征基础上,在四川盆地南部筠连地区开展的物性调查、时频电磁法勘探试验工作。
勘探研究结果表明,本地区分布的富有机质页岩层系-志留系龙马溪组(S1l)具备开展电法勘探工作的物性条件,时频电磁法具有勘探富有机质页岩层系的能力。
关键词:页岩气;非地震勘探;时频电磁法;四川盆地;龙马溪组DOI:10.3772/j.issn.1009-5659.2013.24.034页岩气于1821年在美国东部阿帕拉契亚盆地纽约州Chautauga县泥盆系Perrysbury组Dunkirk黑色富有机质页岩中被发现[1,2]。
页岩气开发,起源于美国,在美国成功实现产业化,正在不断显现出改变美国乃至世界能源供应结构、地缘政治格局的趋势。
由于我国复杂的地质背景,必然导致页岩气形成与富集地质条件的复杂。
针对我国地质条件开展页岩气地球物理勘探技术攻关,研究总结识别富有机质页岩层系的地球物理分布特征,无疑是做好资源调查评价、有利目标区优选工作的关键和重要基础。
采用时频电磁法进行页岩气勘探的研究区,位于四川盆地川南低陡褶皱带南缘,是华蓥山断褶带向西南延伸、呈帚状撒开的雁行式低背斜群,在加里东为坳陷区,印支期为泸州古隆起的主体部分,是中生代以来的隆起区。
川南低陡褶皱带发育NE向、EW向和SN向3组构造,各组构造之间相互影响,呈反接或斜接复合[3]。

Transmission FundamentalsChapter 2Electromagnetic SignalFunction of timeCan also be expressed as a function of frequencySignal consists of components of differentfrequenciesTime-Domain ConceptsAnalog signal -signal intensity varies in a smooth fashion over timeNo breaks or discontinuities in the signalDigital signal -signal intensity maintains a constant level for some period of time and then changes to another constant levelPeriodic signal -analog or digital signal pattern that repeats over times(t+T ) = s(t ) -¥< t< +¥where T is the period of the signal Time-Domain ConceptsAperiodic signal -analog or digital signal pattern that doesn't repeat over timePeak amplitude (A) -maximum value or strength of the signal over time; typically measured in voltsFrequency (f )Rate, in cycles per second, or Hertz (Hz) atwhich the signal repeatsTime-Domain ConceptsPeriod (T ) -amount of time it takes for one repetition of the signalT= 1/fPhase (φ) -measure of the relative position in time within a single period of a signalWavelength (λ) -distance occupied by a single cycle of the signalOr, the distance between two points of correspondingphase of two consecutive cycles Sine Wave ParametersGeneral sine waves(t ) = A sin(2πft+ φ)Figure 2.3 shows the effect of varying each of the three parameters(a) A= 1, f= 1 Hz, φ= 0; thus T= 1s(b) Reduced peak amplitude; A=0.5(c) Increased frequency; f= 2, thus T= ½(d) Phase shift; φ= π/4 radians (45 degrees)note: 2πradians = 360°= 1 periodSine Wave Parameters Time vs. DistanceWhen the horizontal axis is time, as in Figure 2.3,graphs display the value of a signal at a givenpoint in space as a function of timeWith the horizontal axis in space, graphs displaythe value of a signal at a given point in time as afunction of distanceAt a particular instant of time, the intensity of the signalvaries as a function of distance from the sourceFrequency-Domain ConceptsFundamental frequency -when all frequency components of a signal are integer multiples of one frequency, it’s referred to as the fundamental frequencySpectrum -range of frequencies that a signal containsAbsolute bandwidth -width of the spectrum of a signalEffective bandwidth (or just bandwidth) -narrow band of frequencies that most of the signal’s energy is contained in Frequency-Domain ConceptsAny electromagnetic signal can be shown to consist of a collection of periodic analog signals (sine waves) at different amplitudes, frequencies, and phasesThe period of the total signal is equal to the period of the fundamental frequencyRelationship between Data Rateand BandwidthThe greater the bandwidth, the higher the information-carrying capacityConclusionsAny digital waveform will have infinite bandwidthBUT the transmission system will limit the bandwidththat can be transmittedAND, for any given medium, the greater the bandwidthtransmitted, the greater the costHOWEVER, limiting the bandwidth creates distortions Data Communication TermsData -entities that convey meaning, or informationSignals -electric or electromagnetic representations of dataTransmission -communication of data by the propagation and processing of signalsExamples of Analog and DigitalDataAnalogVideoAudio DigitalTextIntegers Analog SignalsA continuously varying electromagnetic wave that may be propagated over a variety of media, depending on frequencyExamples of media:Copper wire media (twisted pair and coaxial cable)Fiber optic cableAtmosphere or space propagationAnalog signals can propagate analog and digital dataDigital SignalsA sequence of voltage pulses that may betransmitted over a copper wire mediumGenerally cheaper than analog signalingLess susceptible to noise interferenceSuffer more from attenuationDigital signals can propagate analog anddigital dataAnalog SignalingDigital Signaling Reasons for Choosing Data and Signal CombinationsDigital data, digital signalEquipment for encoding is less expensive than digital-to-analog equipmentAnalog data, digital signalConversion permits use of modern digital transmission and switching equipmentDigital data, analog signalSome transmission media will only propagate analogsignalsExamples include optical fiber and satelliteAnalog data, analog signalAnalog data easily converted to analog signalAnalog TransmissionTransmit analog signals without regard to contentAttenuation limits length of transmission linkCascaded amplifiers boost signal’s energy for longer distances but cause distortionAnalog data can tolerate distortionIntroduces errors in digital data Digital TransmissionConcerned with the content of the signalAttenuation endangers integrity of dataDigital SignalRepeaters achieve greater distanceRepeaters recover the signal and retransmitAnalog signal carrying digital dataRetransmission device recovers the digital data fromanalog signalGenerates new, clean analog signalAbout Channel CapacityImpairments, such as noise, limit data rate that can be achievedFor digital data, to what extent do impairments limit data rate?Channel Capacity –the maximum rate at which data can be transmitted over a given communication path, or channel, under given conditions Concepts Related to Channel CapacityData rate -rate at which data can be communicated (bps)Bandwidth -the bandwidth of the transmitted signal as constrained by the transmitter and the nature of the transmission medium (Hertz)Noise -average level of noise over the communications pathError rate -rate at which errors occurError = transmit 1 and receive 0;
