济阳坳陷油气精细勘探评价及实践

济阳坳陷是中国陆相断陷盆地的典型代表,先后经历了大型背斜构造勘探阶段、复式油气聚集带勘探阶段和隐蔽油气藏勘探阶段。当前济阳坳陷勘探目标更加复杂、隐蔽,对勘探研究、部署及管理的精细程度提出了更高要求。胜利油田通过强化剩余资源潜力动态评价、持续深化地质规律认识及勘探配套技术攻关应用,开展勘探层单元精细评价,实现了济阳坳陷持续稳定增储。系统总结济阳坳陷勘探实践,提出“五精两创”精细勘探思路方法,对于中国东部同样处于高勘探程度阶段的陆相断陷盆地勘探与稳定发展,具有重要的理论和现实意义。

Evaluation and practice of fine petroleum exploration in the Jiyang depression

As a typical representative of continental fault basin in China,Jiyang depression has experienced 3 exploration stages from structure exploration of large anticlines,complex oil and gas accumulation belts to subtle oil and gas reservoirs.At present,exploration objectives in the Jiyang depression are more complex and subtle,which requires higher elaborate degree of exploration research,deployment and management.By strengthening dynamic evaluation of remaining resource potential,continuously deepening understandings of geological laws and researches and application of exploration supporting technologies,fine evaluation of exploration targets has been carried out in Shengli Oilfield to achieve the continuous and stable reserve increase in the Jiyang depression.This paper systematically summarizes the exploration practice in the Jiyang depression and presents“five fine and two innovative”exploration methods,which is of great theoretical and practical significance for the exploration and stable development of continental fault basins with high exploration degree in eastern China.
