摘要:

利用地震、测井和分析测试资料对塔中地区的输导体系进行了分析,认为断层、裂缝、不整合、岩溶和砂体是构成塔中地区油气运移输导系统的基本元素.不同构造期、不同层序界面输导体系的平面分布特征和纵向演化特征显著不同.输导体系与烃源灶配置网络的有效性决定了塔中地区的成藏效果.区内断裂和不整合非常发育,断裂和不整合是塔中地区油气运移的主要途径;塔中地区具有多期成烃、多运移通道、多期成藏特征,加里东晚期、海西早期和海西晚期是塔中海相油藏的主要成藏期.

Abstract:

Based on seismic,logging,and test data,an analysis was carried out on the carrier systems of Tazhong area,Tarim Basin.The result indicates that faults,fractures,unconformities,karst,and sandbodies are the fundamental components of the hydrocarbon carrier systems in Tazhong area.The plane distributions and vertical evolutions of the carrier systems vary greatly with different structural periods and different sequence boundaries.The effectiveness of the spatial arrangement of carrier system and hydrocarbon kitchen determines the hydrocarbon pooling in the area.Fractures and unconformities are well developed and act as the main migration pathways for hydrocarbon in the area.Tazhong area has the character of multistage hydrocarbon generation,multi-pathways,and multistage hydrocarbon accumulation,with the late Caledonian,the early Hercynian,and the late Hercynian being the main hydrocarbon accumulation periods.

Key words: hydrocarbon kitchen, base unit, carrier system, reservoiring efficiency, Tazhong area, Tarim basin
