According to gathering plentiful relative datum of of Xuer section of Yazihe structure and seismic、 well logging、 surveys、 core ect during the exploitation and exploration,the research starts with analise of slice data、 core observation and core specimens,then combines with coordination、 analyse、 concluding and the former research result.The article recognizes the tectonic feature of Xuer section of Yazihe structure and it"s tectonic evolution,analyzes the distributing feature of oik、 gas、 water、 their dominated factor、 the pressure feature of gas reservoir and especially the conservative condition of Xuer gas reservoir.At the same time,the article acquaintances the depositional feature and sedimentary environment and discusses the main genesis typeof reservoir sandstone.By analyzing the physical feature and physical relation of reservoir rock, the article first classifies and evaluates the reservoir rock simply ,then concludes it"s feature of reservoir and permeability. According to detailed core observation and fracture explanation in well logging ,the article uses single well fracture indentifying and evaluation to confirm the section where the fracture growths,putting emphases on the method to get parameter of fracture,such as fracture width and fracture porosity.Finally,combining with the principal curvature for tectonics deformation the article predicts the plane fracture of reservoir and weave the general evaluation map of crack fracture growth.
