Provenance Analysis of the Fuyu Oil Horizons in the Liangjingdong-mutounan Area of the Southern Songliao Basin

Observed by core description and analysis of a comprehensive analysis of laboratory data,heavier mineral assemblage,sandstone thickness and distribution of sand than that of the plane,the vertical thickness of sedimentary facies and sand provenance in terms of tracking the direction of the judge.The results indicate that there is mainly controlled by two great sediment Southwest Baokang and southern Changchun-Nationwide deposition system.The influence area and intensity changes of each sedimentation system are analyzed synthetically and determined.Provenance have favorable spatial combinationwith depositional system and determine the depositional system pattern of Fuyu oil horizons in the Liangjingdong-Mutounan area of the southern Songliao Basin.Provenance is useful to reasonable deploymentofoil-gas exploration.
