This paper approaches the prediction ways of the high quality reservoirs and the development of fractures and the detection of gas-bearing quality in the deep Upper Triassic Xujiahe Formation gas reservoir in West Sichuan Province.The distribution of high-quality reservoir is predicted by using AVO simultaneous inversion. The joint method of P-wave and convert wave is used to predict the fractures of seismic attribute, P-wave azimuthal anisotropy, shear wave splitting and the multi-scale fractures, and model the discrete fracture net. The results show that those technologies can better predict the reservoirs of relative high porosity,developing fractures and the beneficial gas-bearing areas of Xujiahe Formation.The rate of drilling success is 15%～89%.
