【摘要】 在直接找油气的物探方法中，电法作为一类重要的非地震地球物理方法，越来越受到人们的重视与关注．本文对其中几种主要的方法，如激发极化法、电场差分法和自然电场法等，从原理、发展概况和应用效果方面进行了简要论述．另外，对用来解决地质构造问题的非直接找油气的建场测深法、大地电磁法和可控源音频大地电磁法等，本文也作了扼要介绍．更多还原

【Abstract】 In the geophysical exploration methods for prospecting oil-gas accumulationdirectly, as one of the important non-seismic geophysical exploration methods, electricalexploration is getting morc and more attention and solicitude. From the aspects of methodprinciples、 brief development account and applied effects, this paper discusses some mainelectrical exploration methods briefly, such as Induced Polarization method (IP) 、Differential Normal Method (DNM)、 Self Potential method (SP) and so on.Besides, We also give a brief discussion of some other kinds of electrical exploration meth-ods for prospecting oil-gas resevoir by geological structures, such as TransientElectromagnetic Sounding method (TEMS)、 Magnetolluric method (MT) and Con-trolled-Source Audio-frequncy Magnetolluric method (CSAMT), etc.更多还原
