POU packers for mouth crimping
POU packers for mouth crimping are used to verify the leak-tightness of casing string mouth part and the mounted blowout equipment at pressure, which may occur in case of gas-oil showing, emissions and open flowing, taking into account the auxiliary pressure needed for their elimination.
The packer is mounted on the mouth of the drilling well and the well operated under the pressure following the damping, production tree removal and mounting the preventor rams with a feedthrough hole diameter, which corresponds to the diameter of tubing string descended into the well.
TS 3663-0015-79560377-2009
The packer consists of a hollow stem, on which a self-sealing pump bucket is mounted with the aid of a ring, a plug and a gland nut. Above and below the pump bucket positive centralizers are placed. Sub savers are screwed on stem ends.
