Abstract

Summary

The Ordovician hydrocarbon exploration in the Tazhong area began in the 1990s, and a large ultra-deep marine carbonate condensate gas field has been built now. With the deepening of exploration and development, geologists have gradually realized that the key factors for the formation of carbonate reservoirs in the Tazhong Uplift are the later reformation and effective hydrocarbon enrichment. It is considered that the karst-fracture-type carbonate reservoir of the strike-slip fault damage zone are the main targets of hydrocarbon exploration, and the strike-slip faults cut into the Cambrian are effective channels for hydrocarbon migration. On the basis of previous studies, based on high-precision three-dimensional seismic data, this study aims to geometrically and kinematically characterize the typical strike-slip fault in Tazhong area. Then the sensitive attribute of karst-fracture-type reservoir and a large amount of well production data are further combined to study the influence of the strike-slip fault on reservoir and hydrocarbon enrichment to provide guidance for further efficient exploration and development.
