中文摘要：

充分利用黄海盆地及其邻区钻井、测井、地震等多种资料,综合分析了构造作用对该研究区三叠系青龙组储层的影响,研究结果认为,残存青龙组呈分割状NE—NNE向分布,岩性以碳酸盐岩为主,发育台地、陆棚等沉积相类型;印支—燕山运动时期造成的沉积间断使青龙组遭受强烈的风化剥蚀,形成了储集条件良好的古岩溶储层,其在平面有一定的分布;断裂在青龙组主要为NE向分布,可极大改善储层的性质;初步预测储集条件较好储层主要分布于WX5-ST1井—CZ24-1-1井—CZ35-2-1井一线周围,呈NE向展布。

英文摘要：

An integrated research has been carried out on the tectonic effects on the hydrocarbon reservoirs of the Qinglong Formation in the South Yellow Sea Basin,based on the drilling,well logging and seismic data from the study area and adjacent areas.The relict Qinglong Formation,which consists of carbonate platforms and shelf deposits,is distributed in this region in NE-NNE direction.The Indochina and Yanshan movements made the Qinglong Formation exposed to air for a long term of strong weathering and denudation,and thus resulted in the formation of karst reservoirs that are favorable for hydrocarbon accumulation.The fractures developed in the Qinglong Formation mainly in NE direction further improved the reservoir properties.The reservoirs distributed around the wells of WX5-ST1,CZ24-1-1and CZ35-2-1in a NE trend are selected as the most prosperous ones for consideration.
