摘要
大王庄岩性油藏是华北油田近年来隐蔽油藏成功勘探的一个典型范例。通过分析大王庄东断层下降盘根部负向构造区侵蚀河道砂岩岩性油藏的形成条件,研究了油气运聚成藏过程及主控因素,认为该区生排烃时期与圈闭形成时期匹配良好,成藏时期在明化镇中期,而大王庄东断层的继承性活动,成烃与成藏要素的有机组合是研究区油气富集成藏的主要因素。
The Lithologic oil reservoirs of Dawangzhuang Area has been a typical example of Huabei Oilfield for successful exploration of subtle oil reservoirs in recent years.The geological conditions for forming the erossive sandstone lithologic reservoirs in the downthrown block of east Dawangzhuang Fault were studied.The oil and gas migration and accumulation and the controlling factors were discussed.Period of hydrocarbon generating and expulsion was well matched with that of trap forming period,The reservoir formation period was corresponding to sedimentary middle period of Minghuazhen Formation.The formation of subtle reservoirs is mainly controlled by the timing of hydrocarbon generation and accumulation and fault activity.
