Abstract

Abstract:

Green function and Neumann superposition principle is applied to develop,infinite and finite models of horizontal wellbore and gas reservoir coupling model,and a solution method of this coupling model is given.Comparing infinite model with eclipse software,reasonable results are obtained.The computation of a practical example shows that the pressure drop in wellbore has an important influence in early time of non-steady flow period,the pressuer loss will make the productivity decrease and the pressure distribution non-uniform.Wellbore inflow is more uniform in pseudo steady state than non-steady state.There is a optimal range of the horizontal saction length,aniso-tropic reservoir also has an impact on distribution of wellbore flow.

Key words: horizontal well, wellbore, gas reservoirs, coupling, non-steady
