第二轮油气勘查中的四川物探工作

THE SECOND TURN OF OIL/GAS GEOPHYSICAL EXPLORATION IN SICHUAN PROVINCE

地质矿产部西南石油地质局第二物探大队

本文以1982年地质矿产部系统开展的第二轮石油天然气勘查为重点,阐述了第二物探大队在四川盆地开展物探工作所取得的主要成果和技术进步方面的基本情况。文中介绍了多次覆盖技术、三维地震和宽线地震方法引进到山区后所获得的效果;高分辨地震、转换波地震试验及其显示的潜力和带来的启迪;川西坳陷物探工作获得的进展;地震资料处理质量和效果上的明显提高;地震资料解释的深化及非地震物探资料利用上的探索等等。 作者认为,第二物探大队的前进步伐是与我国石油物探的形势合拍的。通过这个局部,可以从一个侧面来了解建国以来我国石油物探工作所取得的巨大成绩和进步。

The focal point of this paper is about the oil/gas geophysical exploration of the second turn started from 1982 under the guidance of the Geology & Mineral Resources Ministry. The emphasis of it lays on the main achievements and the technology processes achieved by the No.2 Petroleum Geophysical Prospecting Party. Results obtained after the multiple coverage, the 3-D & the WLP techniques have been brought in the mountain area were introduced; potentials shown by the high resolution technique and the converted seismic wave experiment and the enlightenment gained from them were outlined; the achievement of the geophysical work gained in Chuanxi depression was presented; the evident improvement shown on data processing and final resultant, the deepening shown on data interpretation and non-seismic data utilization were all recounted in this paper.The author has the opinion that the pace of the No.2 Petroleum Geophysical Prospecting Party is keeping with that of the whole country. Just for this reason we could say that what we have done could be considered as an epitome of our country in oil/gas geophysical exploration since the founding of the People’s Republic of China.
