石油电法勘探四十年

FORTY YEARS OF CHINA'S ELECTRIC PROSPECTING

在我国地球物理勘探工作的发展历程中,电法(包括电磁法)勘探在50年代中期至60年代中期的石油天然气概查、普查勘探阶段,曾得到了广泛的应用和发展,并取得了明显的地质地球物理效果。笔者将勘探过程划分为三个阶段,即初期阶段(1954年前)、发展阶段(1955—1965年)和缩减提高阶段(1966年以后),并分阶段、分地区简述了石油电法勘探的发展概况和达到的勘探程度,总结了电法勘探的任务和一般采用的方法技术。文章以大量的实际材料说明了电法勘探的地质地球物理效果。

There are three parts included in this paper: briefing introduction, exploration degree and effectiveness. Electric exploration and electromagnetic exploration have been widely used in China during the period from the mid-1950s to the mid-1960s. Attractive results were obtained. In this paper, the author has made a retrospection about the coures of the electric prospecting in China, the history of it could be divived into three periods, the initial stage (before 1954), the developing stage (1955-1965) and the stage of reduction in professional contingents and sophistication in knowledge and equipment (after 1966). Tasks assigned, techniques adopted and exploration degrees reached were delineated according to these three stages and different work ares. Results obtained from electric prospecting were shown by a large number of actual data.
