Abstract: The reservoir of HE-8 Member in Su X well block is typical of low porosity and permeability. The seismic impedance of gas sandstone is greatly overlapped with that of mudstone, therefore the method of reservoir predicting with seismic impedance inversion is not accurate. For the problem above, the method of reservoir predicting with stochastic seismic inversion is proposed in this paper. Geophysical parameters of HE-8 Member are firstly analyzed, in addition lithological and gassy parameters are predicted. On the basis above, lithological and gassy distribution is predicted by means of stochastic seismic inversion. Verified by drilling£?tight reservoir of HE-8 Member in Su X well block is predicted well by this method

Key words: stochastic seismic inversion, reservoir prediction, Sulige gas field, HE-8 Member
