【摘要】 本文利用地震和地面地质资料解剖了酒泉盆地中新生代典型传递带的构造特征,并探讨了传递带对油气的控制作用。早白垩世伸展传递带划分为相向叠覆型、相向平行型、相背叠覆型和横向断层四类典型传递带;新生代挤压传递带分为撕裂断层和横向走滑调节断层,分布于酒泉盆地南缘山前褶皱冲断带,垂直于褶皱冲断带发育,起调节挤压变形和位移的作用。传递带对酒泉盆地油气成藏具有控制作用,伸展传递带不仅对断陷盆地结构和构造圈闭形成起重要作用,而且控制着沉积物源和沉积体系的分布,从而控制着油气的聚集和分布;挤压传递带作为油气运移通道,改善了储层物性,也是青西油田油气富集带。更多还原

【Abstract】 This paper analyzes the structural features of Meso-Cenozoic typical transfer zones in Jiuquan Basin and discusses transfer zone’s oil-controlling based on seismic and outcrop data.Extensional transfer zones in early Cretaceous are divided into four types including synthetic overlapping,synthetic collateral,conjugated divergent overlapping and transverse fault type.Compressional transfer zones in Cenozoic are divided into two types: transverse-slip fault and tear fault.They are mainly distributed in the south marginal piedmont fold-thrust belt,and perpendicularly developed to this belt,which play the role of compressional deformation and displacement.The transfer zones control on formation of hydrocarbon accumulations.The extensional transfer zones not only play an important part in structures and traps developing in the rift basin,but also control the distribution of provenance and sedimentary system,and thus control the hydrocarbon gathering and distribution.As hydrocarbon migration paths,the compressional transfer zones improve reservoir physical properties and they are also rich oil-gas belts in Qingxi Oilfield.更多还原
