前一时期石油电法在我国已濒于灭绝。近年来随着石油勘探形势的发展,能否使电法重新在寻找油气中发挥一定的作用,已引起越来越多的人的关注。从国内外一些资料来看,电法的作用大致在以下几个方面是值得注意的。1.在地震勘探困难区,电法与其它物探资料相配合,解决区域地质问题。内蒙二连盆地就是其中一个典型的例子。该地区地震地质条件复杂,不易获得良好的地震记录,重力异常又有低密度酸性火成岩体的干扰。电法勘探由于高阻标志层埋藏较浅(小于3千米),而较为有利。前几年内,主要利用电法资料,配合重力,正确地提供了区
The previous period of petroleum and electricity law in our country has been on the brink of extinction. In recent years, with the development of the oil exploration situation, whether it can make the electricity law play a certain role in finding oil and gas again and again has attracted more and more people’s attention. Some data from domestic and foreign point of view, the role of electrical law roughly the following aspects are noteworthy. 1. In the seismic exploration difficult area, the electric method is matched with other geophysical data to solve the regional geological problems. Erlian basin in Inner Mongolia is one of the typical examples. The seismic and geological conditions in this area are complex, not easy to obtain good seismic records, gravity anomalies and low-density acid igneous rock interference. Electro-prospecting is advantageous because of the shallow burial of high resistivity markers (less than 3 km). A few years ago, the main use of electrical data, with gravity, the right to provide the area
