摘要
为了研究莱州湾凹陷含油气系统特征，进一步认识油气成藏规律，利用多种钻井资料，结合前人认识，研究了该凹陷构造演化对油气生成、运移与聚集、输导体系的控制作用，探讨了构造演化与含油气系统的关系，指出莱州湾凹陷可以划分为沙四段和沙三段2套含油气系统。其中沙四段含油气系统有东营组末期和明化镇期2个关键时刻；沙三段含油气系统为本区最重要的含油气系统，关键时刻为明化镇期。在上述分析基础上，指出莱西斜坡带和中央构造带为下一步勘探有利目标。
In order to study the characteristics of petroleum system in Laizhou Bay Sag and further understand hydrocarbon reservoir-forming laws, this paper studies the controlling effects of structural evolution on generatlon, migration and accumulation of hydrocarbon and passage system in Laizhou, probes the relation between structural evolution and petroleum system, and points out that Laizhou Bay Sag can be divided into tow sets of petroleum systems, that is, Sha4 Member and Sha-3 Member through application of various kinds of drilling data and combination of understanding from previous researchers. Sha4 petroleum system has two crucial moments, the late period of Dongying Formation and Minghuazhen period. Sha-3 Member is the most important petroleum system in this block, and its crucial moment is Minghuazhen period. Based on the above analysis, it is pointed out that Laixi Slope and central structural zones are the favorable targets of further exploration.
