Abstract：Few studies have been done on the petroleum lateral migration in the newly discovered oil reservoirs in the Jurassic Toutunhe Formation in the Fudong slope,Junggar basin.The process and mechanisms of the petroleum lateral migration of Ju-rassic in the Fudong slope were investigated based on the geological analysis of the strata,porosity and permeability of the res-ervoir rocks and geochemical study on oil-source correlation and oil-oil correlation in this study.The results indicate that hydro-carbons of the Jurassic Toutunhe Formation in Fudong slope were primarily derived from the mixing of the Middle-Lower Ju-rassic and Middle Permian source rocks of the western Fukang depression and migrated along the axis from west to east.The thickness,sand/strata ratio,porosity and permeability of Toutunhe 2 member are all better than those of Toutunhe 1 member, which makes it the main carrier beds of hydrocarbons lateral migration.
