Abstract

With the difficulty increasing of the structural reservoir exploration, lithologic reservoir s become the emphasis of the exploration in Yuanyanggou area of Liaohe Depression. Based on the sequence stratigraphy researches and the theory of sequence and paleogeomorphology controlling sand bodies, the lithologic reservoirs in Yuanyanggou area are studied by using seismic attributes analysis and seismic inversion techniques. The results show that the sand bodies are mainly controlled by paleogeomorphology. the favorable reservoir is fan delta that develops three secondary pore belts with well properties,which is advantageous to the forming of lithologic reservoirs in Yuanyanggou area of Liaohe Depression.
