Abstract: In consideration of the effect of partial penetration of a producing well on gas flow and with the application of transformation by integration,the following series of equations for ideal gas flow in double porous media is derived:An analytical solution of three basic problems is obtained for a formation with infinite boundary,a closed formation with limited boundary and a formation with fixed pressure at the outer boundary.It can be easily applied to fractured oil and gas fields,with practical value particularly in the exploitation of carbonate oil and gas fields with bottom water.
