Oilfield Cementing Hydraulic Liner Hanger Used for Oilwell Completion Tool with Top Packer

SSTP Retrievable Sealbore Packer is a Retrievable Packer. Hydraulically set by pressure in the tubing. It is run with Hydraulic Setting Tool & retrieving is done independently from the Tubing, using a Retrieving Tool manipulated on a work string. This packer is ideally suited for highly deviated well both onshore & offshore.

• The packer can be retrievable, tie-back, large circulation, rotated at large torque and reciprocated with large loads, which can deal with many complex conditions.
• Integral hydraulic setting capacity, and internally-configured barrier module prevents premature setting and hanging caused by circulating pressure.
• The special device of the packer ensures the packer will not set when encountering bump, friction, large torque rotation, large tonnage reciprocating and large circulation. It has high working performance and anti-risk ability to ensure safe running speed ≥30m/min.
• Maximum dogleg severity of packer through casing is greater than 20°/30m; The maximum dogleg severity is greater than 10°/30m and can be set at 100° or more.
• Clean up the well with large circulation. In field operations, the 9-5/8 "packer cleanup rate can reach about 6 BPM. High circulating pressure does not cause the packer to set without dropping the ball.

• Two packing elements are used with high-performance material. The special material of packing element with good sealing performance features in favorable resistance to acid, alkali, oil and high temperature, high pressure.
• There are special sealing and rubber cylinder protection mechanism on both sides of the rubber. The device has high strength and good ductility to fully protect the rubber cylinder and ensure high bearing capacity of the rubber cylinder.
• Hydraulically and mechanically releasing methods for service tools, and a tubing swivel head  installed in the inner string, making a small torque and ensuring reliable operation.
• High-strength premium material with high loading capacity.

• Working principle of top packer

Drop a setting ball and fill string with completion fluid, and hole pressure to shear out the corresponding pins in turn, and push the upper gauge ring to move. The movement of the upper gauge ring unlocks the special locking mechanism, and the rubber cylinder is squeezed and radial elastic deformation is generated to realize setting.
The rubber cylinder also has axial displacement in the radial expansion process. After the shear pin of the retainer ring is cut, the slip cage and the upper cone are pushed to move, while the lower cone has been fixed on the body, so the upper/lower cone will move towards each other, so as to activate the slip, extend the slip, and realize packer setting. After bleed-off in the string, the check ring prevents the component from retracting and remains set.

If the packer needs to be retrieved, run the special retrievable tool to enter the top packer. After in place, lift the retrievable tool to shear the pin of the support sleeve. Meanwhile, the elastic claw of the retrievable tool engages with the left-hand thread on the packer body to lift the drilling tool to retrieve the packer.
