Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.

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.
