摘要：
Strike-slip faults and their reservoir-controlling rules have become the focus of oil and gas exploration, but the internal structural units, transport characteristics and reservoir-controlling rules of different types of strike-slip faults are still unclear. Through detailed fields characterization, physical simulation experiments and typical case analysis, the internal structure of the strike-slip fault and its reservoir control characteristics are revealed. The internal structure of the strike-slip fault includes three units and five zones, including the fault core, the sliding fracture zone on both sides and the induced fracture zone. The fault core of tension- shear strike-slip fault has the best transport, followed by the slip fracture zone and the induced fracture zone. The fault core of compressional or pure torsional strike-slip fault has the best sealing property, followed by induced fracture zone and slip fracture zone. The longitudinal and horizontal transport of tension-shear strike-slip faults is better than that of compression-torsional and pure torsional strike-slip faults. The transport of active disks is better than that of passive disks. The transport of active disks is better than that of static faults. The active disk of the strike-slip fault is characterized by vertical migration of oil and gas in the transport layer while the passive disk is characterized by transverse blocking of oil and gas. The reservoir controlling model of the western strike-slip fault in Jimsar sag, Junggar basin was constructed. © 2023 China University of Geosciences. All rights reserved.
