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

摘要: 郯庐断裂带是中国东部一条巨型断裂构造带,该文从其基本构造特征入手,分析了它的几何学、运动学和动力学特征,并进一步研究其含油气特点,认为:a)郯庐断裂带对中国东部诸多中新生代含油气盆地的形成及演化有重要的控制作用,不同演化阶段产生并控制了不同的沉积盆地(如松辽盆地和渤海湾盆地);b)郯庐断裂带对油气藏的形成及演化有重要的控制作用,不仅控制盆地烃源岩的发育、基本的储集层和盖层条件,以及圈闭的形成等等,而且对油气的生成、运移及聚集成藏、大中型油气田的形成及分布等有重要的控制作用.Abstract: 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.
