THE PROBLEM SOLUTION OF NON-STATIONARY GAS FILTRATION IN THE CIRCULAR CLOSED VARIABLE THICKNESS BED AT NONLINEAR LAW OF RESISTANCE

Flow of gases in a bed occurs at nonlinear law of resistance. This paper describes a solution of problems for variable thickness at the linear law of filtration of gases in a bed. The constant weight discharge of gas wells flow is analyzed in two stages. In the first stage of flow related equations are solved. The investigating gas flow in duration of the first stage is found out in the second stage. The results show that inconstancy of thickness essentially influences contour pressure decline and well production rate of contour pressure. Therefore, the thickness alteration of gas bed based on the solved equations influences well production rate and also bed pressure changing.
