Abstract:The reservoir conditions, oil and gas charge history and accumulation phases were studied for Yingshan Formation of Yuqi block, and an oil and gas accumulation model was established by using the techniques of reservoir prediction, fluorescence thin section and fluid inclusion analysis under the guidance of the theories of oil and gas accumulation. The results indicate that the main rock types in Yingshan Formation are micrite and calcarenite. The carbonate reservoirs are of cave, fracture-pore and fracture types, and their physical properties are intermediate; there are at least four oil/gas charges, i.e. late Hercynian, Yanshanian, early Himalayan and middle Himalayan (Cenozoic). The most important charge periods are late Hercynian, early Himalayan and middle Himalayan; the oil and gas accumulation model is self source—lateral expulsion of hydrocarbon—multistage accumulation, or hydrocarbon sourced from and preserved in the same old rocks—long term expulsion of hydrocarbon—multistage accumulation.

 

Key words: reservoir; oil and gas charge; accumulation model; Yingshan Formation; Akekule arch; northern Tarim Basin
