摘要
胜利油田自1958年开始实施地震数据采集以来,采集技术从二维、常规三维发展到目前的高精度三维。按照勘探目标、地震仪器和采集方法等,二维地震采集技术的发展可分为单次覆盖采集阶段(1958—1972年)、多次覆盖采集阶段(1973—1984年)和高分辨率采集阶段(1985年以后);三维地震采集技术的发展可分为探索阶段(1966—1984年)、发展阶段(1985—1992年)、大规模应用阶段(1993—1999年)和高分辨率(二次)采集阶段(2000年以后)。地震采集技术的每一次进步都带来了油田储量的快速增长,对地下地质情况的认识也由简单构造、复杂断块构造向复杂隐蔽性油气藏逐步深入。
Seismic acquisition technologies in Shengli Oilfield have evolved from 2D, conventional 3D, and 3D of high resolution since its application in 1958. According to exploration targets, seismic apparatus and acquisition methods,the history of 2D acquisition technology development can he divided into three stages:the single-fold stage ( 1958 - 1972), the muhifold stage ( 1973 - 1984 ) and the high resolution acquisition stage ( after 1985 ) ; while the 3D acquisition technology development went through exploring (1966 - 1984 ) , developing (1985 - 1992 ) , large-scale application (1993 -1999 ), and high resolution acquisition (after 2000). Each technical progress results in a rapid growth of reserves in the oilfield and deeper understandings of the subsurface from simple structures, to complex fault block structures, and to subtle reservoirs.
