The development model of modern karst reservoirs was applied in the study of the Ordovician carbonate paleokarst in Tarim Basin to build the karst reservoir development model related to strike-slip faults. High-density electrical logging was utilized for the modern karst area of South China to identify the development characteristics of the fractured-cavernous carbonate reservoirs. In order to clarify the controlling effects of strike-slip faults on reservoirs, characteristics of two types of reservoirs, including strike-slip fault-controlled fracture caverns and strike-slip fault-dissolved fracture caverns in the central Tarim Basin, are delineated through detailed analyses of seismic data, tectonic evolution, and observations of the core and thin sections. Proven to be closely linked to hydrocarbon accumulation, strike-slip faults are important hydrocarbon accumulation zones.
