电法运用到石油勘探方面,国外在三十年代已经开始。我国仅在解放后才开始运用垂向电测深和大地电流法,并在华北、西北、东北等地区的一些大盆地或平原地带进行了大量的垂向电测深工作。以上盆地都有较厚的沉积地层,同时地形比较开阔,地层电性分异明显,因此垂向电测深法的勘探效果是好的,为石油的进一步勘探提供了参考依据。电法在石油勘探方面能起到积极作用,是由于垂向电测深从方法的理论基础到资料的分析解释是比较完善的。
Electric method used in oil exploration, foreign countries in the thirties has already begun. Only after the liberation did China begin to use vertical electric sounding and earth current method, and carried out a large number of vertical electric sounding surveys in some large basins or plains in North China, Northwest China and Northeast China. The above basins all have thick sedimentary strata and at the same time, the terrain is relatively open and the electrical property of the strata is distinct. Therefore, the prospecting effect of vertical electric sounding method is good, which provides a reference for further exploration of petroleum. The electrical method can play an active role in petroleum exploration because the vertical electrical sounding is relatively perfect from the theoretical basis of the method to the analysis of the data.
