1982年地质矿产部召开了“石油地质工作会议”,正式部署了二轮石油普查工作。概括起来二轮普查给物探提出了如下几方面的主要地质任务: 1、了解区域和深部地质问题,进行以圈出油气富集区块(带)为目的的选区评价; 2、普查和发现复杂构造圈闭、非构造圈闭,进行圈闭评价; 3、普查和发现与烃类有关的异常,进行异常评价(与圈闭评价一起同属于面积普查阶段的任务); In 1982, the Ministry of Geology and Mineral Resources held a “conference on petroleum geology” and formally deployed two rounds of oil census work. In summary, the two rounds of census provide the following major geological tasks for geophysical prospecting: 1. To understand the regional and deep geological issues and carry out the assessment of the constituency for the purpose of encircling the oil and gas-rich areas (belts); 2. The census and the discovery of complex Structural traps, non-structural traps, trap evaluation; 3, census and discovery of hydrocarbon-related anomalies, the anomaly evaluation (together with the evaluation of the traps belong to the task of area census stage);
