Research On Reservoir-Forming Rule In Changchunling Anticline Belt Middle-shallow Layer Of Song-liao Basin Southeast Uplift Area

This article relies on the exploration Status of changchunling anticline belt of song-liao basin southeast uplift area entire southeast uplift, a combination of the latest theories and methods of sequence stratigraphy, sedimentology, structural geology, petroleum geology,seismic stratigraphy etc., the use of seismic, well logging, mud logging, core analysis data, to analysis and research on the southeast uplift Changchunling anticline belt sequence stratigraphy framework, sedimentary facies. On this basis, the comprehensive use of petroleum geology, geochemical analysis testing data, research on source reservoir cap assemblage rule in study area, and prediction of middle-shallow layer oil and gas exploration in favorable zone.The study on the southeast uplift Changchunling anticline belt 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, 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. The secondary oil is mainly from Yingcheng group and Shahezi group.The paper comprehensively consider source reservoir cap trap ect.basic conditions for the formation of reservoir ,predicts favorable perspective plays...
