摘要
Based on the studies of fault sealing evolution,oil-bearing formation and hydrocarbon generation ability of highly-conductive mudstones in the Dainan Formation,the fault-lithologic reservoir systems of the Dainan Formation in the Gaoyou Sag have been classified into 3 types,including self-sourced,other-sourced and mixed-sourced.The self-sourced accumulation systems mainly locate in the deep Shaobo and Fanchuan Sags,and the Shaoshen1 resrvoir is typical.The other-sourced accumulation systems mainly distribute in the Majiazui,Zhou22 and Shao18 reservoirs.The mixed-sourced accumulation systems are represented by the Lian3,Lian7 and Yong22 reservoirs.The fault-lithologic reservoirs of the Dainan Formation in the Gaoyou Sag are controlled by2 elements,oil source and migration pathway.The favorable zones for exploration include Huangjue-Majiazui,Lianmengzhuang Yongan and Caozhuang-Xiaoliuzhuang.
