| Abstract: | Skin factor of near wellbore zone is an important parameter to evaluate productivity and completion efficiency of oiland gas wells. However, the skin factor determined by pressure buildup curve of gas well is a total skin factor which includespenetration degree skin factor, perforation density skin factor, high velocity turbulence skin factor and mud damaged skin factor.Based on concerned references [1-6], a decomposition method of the skin factor of gas well is proposed in this paper. Theeffectivity of the method is indicated by case applications. |
