在综合物化探勘探油气藏中,电法的应用得到了重视。本文简述了国内外应用激电法寻找油气藏的概况,概述了川西地区的地质、地球物理特性,介绍了激电法在川西油气田上的应用效果,分析了影响测区激电法勘探效果的主要原因。最后指出了激电法寻找油气藏的局限性,以及为了进一步提高激电找油气的效果,在激电工作中应当注意的问题。

In oil and gas exploration by comprehensive geophysical and geochemical methods, the use of electrical method is took seriously. In the paper, we briefly narrate the state of seeking hydrocarbon reservoirs by the induced polarization method in China and abroad, summarize the geological and geophysical featrues of the western Sichuan area, introduce the effect of induced polarization method applied to western Sichuan oil and gas field, and analyze the main cause of influencing the exploration effect of induced polarization method. Finally, the limitation of seeking hydrocarbon reservoirs by the induced polarization method is pointed out. In order to further improve the effect of seeking oil and gas by the induced polarization method, some problems which should be noted are pointed out as well.
