我国于一九五二年始,开展了石油电法勘探工作,五十年代末,石油电法队发展到36个。六十年代初,随着石油勘探重点由西北转向东部沿海,以及后来“文革”的影响,电法队大批的压缩和转业。七十年代初重新集结了五个电法队,不仅继续从事石油电法勘探工作,而且还开展了直接找油的试验工作。这一期间还就电法勘探的某些应用理论进行了深入研究,建立了一整套数字处理程序。从三十年来的电法勘探实践可以看到,电法勘探在区域普查、查明局部高阻层隆起以及在特殊条件下对电性断面的研究等方面,仍然能起到重要的作用。今后,要积极发展和研究大地电磁测深、建场测深等其他电勘探方法,加强这些方法的综合应用。
In 1952, China started its exploration of petroleum and electricity law. In the late 1950s, the number of petroleum and electricity law teams had grown to 36. In the early 1960s, as the focus of oil exploration shifted from the northwest to the eastern coast, and later the “Cultural Revolution”, the large number of electric law teams collapsed and were switched to jobs. The early seventies regrouped five electric law team, not only continue to engage in oil and gas exploration work, but also to carry out direct oil test work. During this period, some applied theories of electrical prospecting were further studied and a complete set of digital processing procedures was established. From 30 years of practice of electrical prospecting, we can see that electrical prospecting still plays an important role in regional census, ascertaining local high resistivity layer uplift and researching electrical section under special conditions. In the future, we will actively develop and study other methods of electric exploration, such as electromagnetic measurements of the earth’s surface and depth measurements of the site, to enhance the comprehensive application of these methods.
