A gas pool in the Tarim oilfield is a typical of ultra-high pressure fractured gas reservoir,with deep burial,high pressure,high stress,natural fractural development,and thick bed.The general fracturing is not well fitted,while the multistage fracturing plays a good role.To resolve the difficulties of the multistage fracturing for the ultra-high pressure fractured gas reservoir,we optimize the multistage fracturing tools with well completion packer,fracturing packer and sliding sleeve.We use the logging stress integration and optimizing perforation simulation technology to optimize the layering.We deploy the weighted fracturing fluid with density of 1.32 g/cm3 to decrease the tubing pressure.The high pressure equipments are used to fit the requirement of high tubing pressure.The result and experiences of the multistage stimulation of HTHP fractured deep gas reservoir is helpful to other gas reservoirs.
