It is essential to establish the productivity model of gas well considering stress sensitivity in low permeability gas reservoirs. The cores from Tarim low permeability gas field were adopted for stress sensitivity experiments. The experiment results show that the low permeability cores present strong stress sensitivity. With the decline of permeability, the stress sensitivity coefficient rises, and the stress sensitivity becomes strongly. The seepage area of fractured gas well is divided into two parts: One part is the radial flow around the two ends of fractures; The other part is the linear flow along fractures. Then the gas well productivity model considering stress sensitivity is deduced. The stress sensitivity has a significant impact on the productivity of fractured gas well. The stronger the stress sensitivity of gas reservoirs is, the higher the productivity loss rate is. With the decline of flowing bottom hole pressure, the productivity loss increases due to the stress sensitivity. Fracturing is an effective method for improving the productivity of gas well affected by stress sensitivity in low permeability reservoirs., authors=HOU Yong^1,2, TANG Rui³, authorsList=HOU Yong, TANG Rui, authorCompany=1.
