Abstract: In the process of developing the deformed double porosity media reservoirs, the rock stress-sensitivity will apparently effect the performance of development. In this paper, the deformed double porosity mathematic
model is established and the permeability stress-sensitivity is presented on the basis of considering double porosity media and deformable performance of rock. Through Laplace transformation, the Laplace space analytic solution
has been obtained and converted into real space solution by means of the numerical inversion of Stehfest and the solution of the mathematic model is obtained. On the basis of the varying relation between the dimensionless rate and dimensionless time, the influence of the storativity ratio, the interporosity flow parameter, the dimensionless stresssensitivity and skin coefficient on gas well flux dynamic characteristics has been analyzed. The research result is
of actual significance to develop deformed double porosity media reservoirs reasonably and to ensure the normal production of the gas wells or reservoir.

Key words: deformed double porosity media, stress-sensitivity, flowing, dynamic Characteristics, mathematic model
