Tazhong Gasfield located in the hinterland of Taklimakan Desert.The main development series are the carbonate reservoir in the Upper Ordovician Lianglitage Formation and the Lower Ordovician Yingshan Formation.The gasfield has active edge-bottom water,and failure development pattern.At present there are 126 wells and gasfields.With the decrease of formation energy,the well fluid energy drops,and the wellbore is full of fluid,affecting the normal production of gas well,which seriously affected the efficient development of gasfield.According to the investigation,the coiled tubing speed string can solve the problem of shaft tower gas effusion.As the first coiled tubing speed string drainage gas recovery test in the Tarim Oilfield,well D2 acquired a certain increasing yield.The tests obtained some preliminary achievements.This technology can solve the problem of single well wellbore effusion in the gasfield in the Tazhong.
Key words：
Wellbore effusion; Coiled tubing string; Formation energy
