For a start, before the seismic inversion it is essential for a reservoir to enhance the basic research of the rock geophysical characteristic analysis, horizon calibration, fidelity processing and model analysis, etc., and of the reservoir's lithologic character, physical, electrical and gas bearing property. Subsequently based on the fundamental principle of seismic inversion, a series of inversion methods and their application conditions were emphasized. Finally, taking Labureng area as a target, by comparing various inversion effects, we aimed at enhancing the precision of seismic image, increasing SN ratio and resolution, and highlighting seismic responses of the target strata, and presented reliable geophysical references for the understanding of reservoir evaluation, gas bearing modelbuilding and reservoir mechanism in HJQ area.
