摘要
The analysis of latest 3D seismic data shows that strike-slip fault system occurred in the Cambrian-Ordovician marine carbonate rocks in Tarim Basin. The structural styles appeared in flower structure, en echelon structure, pull-apart graben, braided structure,shear fault zone, etc. It is concluded that the formation and evolution of strike-slip faults are characterized by multiple stages, the faults development by inheritance and segmentation. The strike-slip faults are of great effects on the carbonate reservoirs. The early paleo-reservoirs were destroyed by the strike-slip faults which became the main passageway for late hydrocarbon migration and accumulation. The segmentation of hydrocarbon distribution resulted from the strike-slip faults.
