CHARACTERISTIC OF TECTONIC EVOLUTION AND PETROLEUM GEOLOGY IN LISHUI SAG, EAST CHINA SEA BASIN
东海陆架盆地丽水凹陷构造演化及油气地质分析

Lishui sag lies in the west of Taibei depression. It is a fault subsidence which developed during the Cenozoic Era. It is one of the best potential basin in the East China Sea continental shelf and experienced two tectonic stages and four periods. In this paper, we analyzed the condition of petroleum formation and accumulation in Lishui sag. And we divided the oil-bearing system in the Lishui sag. Therefore, the Lishui sag is considered an important hydrocarbon source system and target for exploration due to its great hydrocarbon potential.
