渤中坳陷断裂构造特征与油气运聚关系研究

渤中坳陷位于渤海湾盆地中心部位 ,是渤海湾盆地地质结构、构造演化和盆地充填都比较独特的地区。本文从该地区的构造演化入手 ,详细探讨了渤中坳陷断裂构造的独特特征及其对本地区油气运聚的影响 ,认为坳陷内主要断裂的长期活动控制了烃源岩的发育与分布 ,促进了油气的垂向运移 ,形成了丰富的圈闭类型 ,并且对油气的保存条件也有一定的影响。总的来说 ,断裂带是渤中坳陷有利的油气聚集带

Study on the Relation Between Associated Gas Accumulation and Structural Characteristics of Cenozioc Faulted Structure in Bozhong Depression

Bozhong depression is located in central part of Bohai Bay basin. Faulted structure of bozhong depression has its own characteristics. Starting with structural evolution of this area, the paper is intended to detail the peculiar characteristics of faulted structure in Bozhong depression and its effects on associnated gas in this area, at the same time,it is conclued that the long-term performance of main faults of Bozhong depression controls the distribution and evolution of hydrocarbon source rock,hastens vertical migration of hydrocarbon,forms abundant trap styles,and has some effect on conservation of hydrocarbon.In a word,fault zone is favourable to hydrocarbon accumulation zone of Bozhog depression.
