摘　　要：利用输导体地质综合研究方法,以断层、砂体及断-砂组合关系分析为基础,对准噶尔盆地白垩系油气成藏体系进行研究,分析网毯式油气成藏体系输导体的特征及分布。结果表明:按照输导体与毯状仓储层中底砾岩的接触关系,可建立3类9型输导体样式,包括上沟通型、下沟通型、自沟通型、内沟通型断裂输导体,沟通型、未沟通型不整合面输导体,上沟通型、下沟通型、内沟通型砂体连通输导体;不同类型的输导体组合出'Y'型输导模式、'T'型输导模式、'H'型输导模式;输导体在仓储层的'成毯'和'溢散'过程中起到关键作用;复杂的网状输导体系控制了研究区油气藏的形成、分类及分布特征。Using the the geological comprehensive study method of transportation system, the hydrocarbon accumulation system of Cretaceous in Junggar Basin was studied based on fault, sand body and matching relationship of sand-fault. The characteristics and the spatial distribution of transportation system of meshwork-carpet type hydrocarbon reservoir system were analyzed. The results show that three classes and nine types of conductor department styles are defined according to the contact relationship between elements of transportation systems and basal conglomerate of storage layer. It includes upper-connected type, down-connected type, all-connected type and inner-connected type of fault transportation system, connected type and non-connected type of unconformity transportation system as well as upper-connected type, down-connected type and innerconnected type of sand body connected transportation system. Different types of transportation combinations make three transportation models of oil and gas about ＂Y＂ type model, ＂T＂ type model, and ＂H＂ type model. Transportation system plays a key role in the process of making carpet and diffusion in storage layer. Reticular and complex transportation system control formation, classification and distribution of oil and gas reservoir.
