Research On Reservoir-Forming Rule In LiShu Depression

The latest theory and method of sequence stratigraphy, sedmentology and seismic straligraphy are adopted in this paper. By using the data of seism data, log data, core information, the framework of sequence strata and sedimentary facies in LiShu depression are analyzed and studied deeply, also the advantageous targets are researched and forecasted primarily. The fruit enrich the theories of sequence stratigraphy and sedimentology. All researching will play an important role in exploration and development of this area.The study on the southeast uplift Lishu Depression oil and gas sources, source rock quality and hydrocarbon supplying ability of source rocks etc. hydrocarbon source detailed analysis and research. Through the relevant geochemical indicators, including source rock organic carbon, chloroform bitumen "A" content analysis, obtained in middle-shallow layer the original oil and gas sources of oil and gas, mainly from Qingshankou group and Denglouku group, but the number of less difficult to form large-scale oil and gas reservoirs, in middle-shallow layer should still mainly look for the secondary oil and gas reservoirs, its oil and gas mainly comes Yingcheng group and Shahezi group.This paper comprehensively consider source reservoir cap trap ect.basic conditions for the formation of reservoir ,predicts favorable perspective plays.
