近几年来电法勘探在普查和勘探石油构造方面做了不少工作,特别是在1958年全国大跃进的形势下电法勘探(主要是垂向电测深法)工作效率比原定额提高了五倍到十倍。几年来电法在石油勘探方面的工作效果也是良好的,不同比例尺(1/100万,1/50万,1/20万)的测量,对划分不同等级的区城地质构造起重要作用,它可以比其它方法更正确地反映标志层(以一定地质时代,一定岩相为前提)的超伏情况,它可以清楚地告诉人们沉积岩的厚度甚至岩相方面的资料。电法勘探在勘探以标志层为目的的局部隆起也有良好效果。
In recent years, electrical prospecting has done a lot of work in census and exploration of petroleum structures. Especially in the situation of great leap forward in 1958, the working efficiency of electrical prospecting (mainly vertical electrical sounding method) is higher than the original quota Five times to ten times. In recent years, the effect of electrical method on petroleum exploration is also good. The measurements at different scales (1 / 1,000,000, 1 / 500,000, 1 / 200,000) play an important role in the division of geologic structures of different levels in the city. It can more accurately reflect the ultra-volt-age of the marker layer (under certain geological times and certain facies) than other methods. It can clearly tell people the thickness of sedimentary rocks and even the lithofacies information. Electrical prospecting also has good results in the exploration of local uplift for the purpose of marking.
