Sand body prediction of Fuyu Oil layer in 401 block, Sanzhao Depression, Songliao Basin

This paper takes Sanzhao Depression in Songliao Basin as the research target, Fuyu oil layer in Sanzhao Depression is an important petroleum exploration field, it is in the 4th member of Quantou formation, Lower Cretaceous.The target layer in research area is mainly a set of shallow-water delta deposition.Because of the distributary channel frequently swing, single sand body thin thickness, study of sand body prediction must be carried out to guide further petroleum development.In the case of lack of core data, this study use the method of geostatistical inversion to predict sand body.The sedimentary facies make a certain control to the sand body distribution.
