A STUDY OF HYDROCARBON-BEARING CHARACTERISTICS IN THE TANCHENG-LUJIANG FAULT ZONE

The Tancheng Lujiang fault zone is a vast structural zone in East China.Based on its basic structural characteristics,the geometry,kinematics and dynamics of the zone were analyzed and the hydrocarbon potential of basins around it was studied.It can be concluded as followings:(1) The formation and evolution of the Meso Cenozoic petroleum basins,such as Songliao Basin and Bahaiwan Basin in East China,were mainly controlled by the Tancheng Lujiang fault zone;and (2) The fault zone also played a very important part in formation and evolution of hydrocarbon pools.It controlled the development of source rocks,reservoirs and cap rocks and the generation,migration and accumulation of hydrocarbon in a basin.The occurrence of large or medium oilfields was closely related to the fault zone.
