摘要
Based on the interpretation of seismic data and the compilation of structural maps, the present paper studied the type and distribution of strike-slip fault systems in Bohai Basin, and discussed their formation dynamics and significance in petroleum geology. Strike-slip fault belts in Bohai Basin are dominated by en echelon normal-fault systems and synthetic shear-fault systems, with some antithetic shear-fault systems and secondary synthetic shear-fault systems occasionally. The assemblage of shear-fault systems indicated a right-handed wrenching action occurred in late Neogene-Quaternary. The formation of strike-slip systems was indicative of the reactivity of the Tanlu Fault, a result of the long-distance impact by the collision between the Indian and Euroasian plates. The strike-slip systems formed significant petroleum traps, thus, they are favorable areas for future petroleum exploration.
