Study On Condition Of Oil-gas Reservoir Forming And Target Of Exploration In Kenxi Area

Geological feature of Kenxi area is described from the analysis of evolution history of structure, accumulation, organic geochemistry and dynamic system of reservoir. The structural elements of controlling reservoir forming in Kenxi area are studied and estimated systematically ,The vertical and plane evolutionprocesses of sedimentary in Kenxi area are set forth, Time and space spread and its controlling factors of the hydrocarbon source rock and reservoir are analyzed, two types of hydrocarbon source rock(Es3, Es4), two types of heavy oil, two periods of hydrocarbon generation ,two periods of hydrocarbon drain, two stages of reservoir forming and five dynamic systems of reservoir forming are definite in Kenxi area . The special characteristics about generation , drain, accumulation of hydrocarbon in Kenxi area are analyzed systematically , Distribution rules of reservoirs are analyzed based on the structural and depositional features of Kenxi area. The pattern and main controlling factors of reservoir forming and the distribution rule of the oil-gas in Kenxi area are found, especially the geological condition of oil-gas reservoirs forming and the distribution rule of subtle reservoirs are found too. The knowledge about slope break belt is put forward, it is point out that the slope break belt in Kenxi area is the controlling factors of oil-gas distribution and reservoir forming by enrichment, it is is favorable zones of exploration in the future. At last, the train of thought is put forward in accordance with distribution properties of the pool in Kenxi area, Now progress of exploration in Kenxi area have been obtained, good results have been obtained in exploration practice.
