Abstract

The application of partially completed horizontal well is very promising,but the relevant researches worldwide are only based on oil reservoir. According to the stable percolation theory of gas and three dimensional seepage characteristics of horizontal well,the pseudopressure distribution of infinitesimal horizontal section influenced by non-Darcy flow was derived by introducing skin factor related to flow rate. Furthermore,based on the superposition principle of pseudopressure drop,the gas reservoir model for partially completed horizontal well was established. And the coupling model for production prediction was founded by coupling gas reservoir model and wellbore model. The verification for this model against reality case indicates a high accuracy. Utilizing this coupling model,the predicted production and the distribution of flow rate,axial production and flowing pressure in wellbore along horizontal well of partially completed horizontal well are obtained.
