摘要

大港油田历经40余年勘探与开发,构造带主体基本已探明,勘探难度日益增大,以前未得到重视的由凹陷向正向构造单元过渡的斜坡带将成为今后寻找地层岩性油气藏的重要领域。以位于凹陷向凸起过渡斜坡区的沙三段为例,开展古地貌恢复研究及有利砂体预测,明确空间展布范围。在沙三段油气成藏条件综合分析的基础上,建立该区“凹—断—坡—隆”深层岩性油气藏成藏模式,并得到钻探验证。进一步展现出北大港构造带北翼良好的勘探潜力。

Abstract

After more than 40 years of exploration and development in Dagang oilfield,the main structure has been explored fundamentally and exploration difficulty is increasing by degrees.The extensive slope zones between the sags and the uplifts,which were not attention-getting previously,will become an important research field in future.Taking example for Es3 of the slope zones,on the basis of synthetical analysis of hydrocarbon reservoir accumulation in Es3 ,we establish lithologic hydrocarbon reservoir accumulation model of “sag-fault-break-uplift” in deep zone of this area by means of palaeogeomorphic recovering research and beneficial sand body predication.The model has been validated by exploration drilling,and shows good exploration potential in northern Beidagang buried hill structural zone.
