在前人研究的基础上,利用最新的地震和钻井资料,分析了巴楚隆起西段与麦盖提斜坡过渡区色力布亚、康塔库木两条边界断层的构造特征.色力布亚和康塔库木断层均表现为基底卷入型逆冲断层,两条断层之间通过软联接的形式发生相互作用.色力布亚断层沿其走向往南东方向位移量逐渐减小并终止,康塔库木断层沿其走向往南东方向位移量逐渐增大.构造转换带传递了色力布亚断层和康塔库木断层的位移量,使巴楚隆起西段边界断层总位移量保持一致.该转换带属于同向倾斜型构造转换带,现今处于转换带复杂阶段.转换带内发育次级断层和走向裂缝,有利于形成裂缝型油气藏,也是油气运移的有利通道,是巴楚地区未来油气勘探的重要目标.
Based on the previous studies, based on the latest seismic and drilling data, the structural features of the two boundary faults of the Tarimya and Kangtakumu in the transitional section of the Bachu uplift and the Maigaiti slope are analyzed. Both the Yakunkangkutu fault and the Kuntakut fault act as basement thrust faults, and the two faults interact with each other through soft joints. The displacement of the Tarimya fault decreases along its strike toward the south-east direction , The displacement of Kangtakumu fault increases along its strike towards the south-east direction.The tectonic transitional belt transfers the displacement of the Keruibuya fault and Kangtakumu fault so that the total displacement of the boundary fault in the western segment of the Bachu uplift The conversion belts belong to the same directional tilting structural transformation zone and are now in the complex phase of the transformation zone.The development of secondary faults and strike fractures within the transformation zone is favorable for the formation of fractured reservoirs and favorable channels for hydrocarbon migration, It is an important target of future oil and gas exploration in Bachu area.
