Yushulin Oil field area to the east of the study area is located in the, regional structure across the central depression of the northern Songliao Basin of the depression area in Sanzhao depression to the East Yushulin nose like structure, Hao Jia nose like structure, too Pingchuan anticline and northeast uplift area in Suihua sag is a nose like structure. At present, the research area in the west of the tree 3, 20 and other well areas have been reported to the proven reserves and has been put into development. The area is 25, 4 and other well areas are controlled reserves, and the 301 well area of the tree is the forecast reserve area. Urgent need through fine structure, reservoir recognition, further implementation of the scale of reserves, block selection, guidance and evaluation wells to deploy and reserve upgrades, and to find a new potential resource area.Under the high resolution sequence stratigraphy theory, according to the phase controlled sequence comparison principle established reservoir subdivision and correlation framework, the reservoir subdivision and correlation of strata; application of 3D seismic data, well log and seismic method of typical block structure, fault of new understanding; application of seismic attributes and seismic inversion technology describes reservoir prediction and the main sand body; for the next step reserves evaluation and optimized blocks lay the foundation.Fuyang reservoir of study area mainly developed meandering river, Delta and lacustrine phase, which meandering river and delta plain, distributary channel is the most favorable reservoir facies, channel sand body is banded or patchy distribution, distribution changes rapidly. The main river in the North West, North East trending. Yangdachengzi reservoir sand body is Fuyu reservoir, sand body in the vertical direction is "mud pack sand" feature. The source distribution of the sand body is obvious in the plane.
