Product Name:Y341 series hydraulic packer
Product Description:Y341 series cup packer is a downhole tool which is mainly used for the seperated layer water injection, high-pressure water injection, acidification and squeeze.
Principle: Y341 series cup packer is made up of actuating unit, sealing assembly,setting locking system, flush valve assembly, Deblocking orgnization,when seal the packer,high pressure liquid promote well flushing plunger ,seal the well flushing passage of the internal and external central tube,simutaneously promote the setting plunger go up,it also has plunger lock set and the rubber drum radial deformation of Rubber tube holder upward compression ,in the mean time, Snap ring into the sawtooth of lock sleeve.lock the radial deformation barrel ,let the packer seal the casing annulus space all the time.
During the inverse well-flushing, wellhead high pressure fluid effect on the well washing plunger by means of inlet opening which is above the sealing section, lower the well flushing plunger ,open the well flushing passage,the high pressure water enter into the oil sleeve annular space which is beneath of sealing rubber barrel through the passage of Inside and outside center tube,back to the ground from pipeline through the bottom ball seat.
Deblocking: lift tubular column, then the deblocking is achieved.
Main features:
1) Y341 series cup packer can supply circulate setting.
2) Y341 series cup packer add the balance piston.
