摘　　要：总结了“九五”以来东濮凹陷新增探明储量恢复性增长的成功经验和关键技术 ,应用圈闭法对东濮凹陷滚动勘探开发效果及潜力进行了研究。研究结果表明 ,东濮凹陷滚动勘探开发的潜力还很大 ,剩余油气资源主要分布在下第三系沙河街组 ,尤以沙三段断块型和岩性型圈闭最突出 ,剩余石油资源量为 5 .38× 10 8t,天然气为 10 74× 10 8m3 ,分别占全凹陷剩余油气资源量的 74 .8%和 5 8.4 %。平面上 ,剩余油气资源量分布在前梨园洼陷西侧、文留东部及卫城与濮城结合部的环洼带 ;纵向上 ,石油剩余资源分布在 2 0 0 0～ 4 0 0 0m深度内 ,而天然气剩余资源则主要分布在 35 0The rolling exploration and development achievements and key techniques for Dongpu sag in the 'Ninth Five Plan' period are summarized. The residual resource potential and rolling exploration and development effectiveness in this area were analyzed. The next thinking way and methods for rolling exploration and development were put forward. It is pointed that the remaining oil and gas distributed in Shahejie formation of Paleogene, especially in the fault block and lithological pool of the third member in Shahejie formation. The remaining oil source is mainly located in the ring sag belt with the depth from 2?000 to 4?000 meters, and remaining gas source is located in the deep oil gas reservoirs down 3?500 meters.
