The main reservoir in the Sulige gas field lies in the sandstone of the Segment He8 braided river channel. The sand body varies quickly in lateral direction, and it is difficult to predict for little difference of impedance between gas bearing bed and surrounding rocks. According to petrophysical analysis, some elastic parameters such as PS velocity ratio, Poisson ratio, λρ could reflect the informations about hydrocarbons in the formation. Based on the Swave prediction, we carried out prestack seismic inversion in the Sulige district and gained good results which provides an important method for the hydrocarbon bearing prediction in this area
Key words： Pre; stack inversion; S-wave forecast; Petrophysical analysis; Elastic parameters.
