摘要

A kind of system is used for injection treatment fluid injection wells, which includes: a kind of surface controlled subsurface safety valve; Valve controls conduit, from surface to the well head of controlled downhole safety valve pit, wherein controlling conduit by changing Fluid pressure surface controlled subsurface safety valve valve; A kind of fluid injection opening valve control conduit is for treatment fluid to be discharged into well; Treatment fluid injection catheter is arranged to control conduit with the first valve; At least one treatment fluid injection opening; With an one way stop peturn valve, prevent fluid from entering valve control conduit via conduit from each treatment fluid treatment fluid injection pipe injection opening in this way, wherein treatment fluid injection conduit is ordered in one section of well and carries out that at least one treatment fluid injection opening is made to be to be located at surface controlled storm valve positioned at surface controlled storm valve.
