摘要
Based on the interpretation of the new drilling and seismic data,the structural characteristics of the Selibuya fault and Kangtakumu fault,which are the boundary faults between the western Bachu uplift and Maigaiti slope,are analyzed in this paper.The Selibuya and Kangtakumu faults are basement-involved thrust faults interacting by soft-linkage.Along the SE strike,the displacement of the Selibuya fault gradually decreases,while the displacement of the Kangtakumu fault increases.The transform zone between the two faults transferred their displacements,and kept the conservation of fault displacements in western part of the Bachu Uplift.The transform zone belongs to the synthetic overlapping zone which is in the evolution stage of complex.There are much secondary faults and fractures,which is good basis for the formation of fractured-type reservoirs and hydrocarbon migration.The transform zone is the favorable objective for petroleum exploration in the Bachu area.
