摘要 通过利用地震、钻井、测井及分析化验等资料对胡力海洼陷烃源岩条件、沉积特征、储层条件、运移条件、盖层因素进行分析,弄清了胡力海洼陷油气成藏的主控因素,该地区油气成藏受构造带与沉积相分布控制明显。研究表明,众多断块、断鼻构造对油气封堵起着重要的作用,缓坡带为构造油气藏的主要聚集地,近岸水下扇相及扇三角洲前缘相为有利的储集相带,因此该研究区具有较好的成藏条件。 The data by of seism,drilling,logging and testing are used to analyze the conditions of hydrocarbon source rocks,the sedimentary characteristics,reservoir conditions,migration condition and caprocks of Hulihai Sag,it is found out that hydrocarbon accumulation is controlled by tectonic belt and sedimentary facies distribution which are the main controlling factors of hydrocarbon accumulation in the Hulihai Sag.The result shows that many fault blocks and faulted nose structures play an important role in sealing off oil and gas reservoirs,gentle slope belt is the main place of accumulated hydrocarbon reservoirs,and near shore subaqueous fan facies and deltaic front facies are favorable reservoir facies belts.Therefore,the researching area has good accumulation conditions.
