| 摘 要： | 莱州湾凹陷近年获重大油气发现,但构造演化特征复杂,烃源岩、沉积体系展布特征以及油气运聚规律认识尚不够深入.本文利用多种钻井资料,结合区域地质研究,首先对本区构造演化所产生的断裂与圈闭特征进行分析,划分出3级断裂体系以及3种类型圈闭,并深入研究了构造演化对油气生成与演化、优质储盖组合的分布以及油气运移与聚集的控制作用,总...

| Abstract: | There are significant discoveries in recent two years in Laizhouwan depression，however，the distribution of source rock and sedimentary system，as well as hydrocarbon migration and accumulation，are not deeply studied for the complicated Structure Evolution characteristic.Based on well drilling as well as regionally geological study，this paper analyzes fault and trap characteristics，and classified three types of fault system and trap for the first，then studies the effect of structural evolution on hydrocarbon generation and evolution，distribution of high quality reservoir seal combination，hydrocarbon migration and accumulation.At last two reservoir forming patterns are concluded and the next favorable exploration targets are pointed out. |
