Stability of inverse convolution calculating method has been resolved by Schroeter、Hollaender and Gringarten which makes it applied in well testing interpretation.

But as for the percolation problem of non-closed boundary, routine method did not work effectively, the Boundary Element Method to study the non-closed boundary mathematical model of well testing interpretation was presented in the paper, which was Laplace transform to the percolation differential equation, the solution in the Laplace.

According to the well testing interpretation, the pays of all the wells in Penglaizhen gas reservoir of Baimamiao are polluted at different levels, the percolation features of the pays are complicated, the permeability near borehole is good and the permeability far from borehole is poor.

Conventional well test analysis has become matured as to application in homogeneous reservoir and single-phase flow, while theories and methods of numerical well test analysis are rarely used as a new technology.

A dynamic analysis method, which includes well test analysis and productivity analysis and integrates with static and dynamic data of a reservoir, can be used to calculate the value of K/μ.
