Analysis of Influence Factors of Shale Oil Formation in Zhanhua Depression of Bohai Bay Basin

According to the organic geochemical analysis of the third member of the Shahejie Formation mud shale,oil was mainly generated by the source rock in Zhanhua Depression,Bohai Bay Basin.The oil generation potential of the third member of the Shahejie Formation shale was great.Based on the analysis of tectonic movement,the time of fault activity,hydrocarbon generation threshold determination of the source rock,and shale oil exploration situation,the research results have shown that the third member of the Shahejie Formation shale oil generation potential was great and the mud shale fracture developed.Hydrocarbon migrated after tectonic movement and magma intrusion stopped,and migrated to the mud shale fractured reservoir.The geological condition is conducive to shale oil and mud shale has a great exploration potential in Zhanhua Depression.
