Introducing the SSTP Retrievable Sealbore Packer, a top-tier Retrievable Packer tailored for excellence. Ingeniously hydraulically set using tubing pressure, this Packer is deployed with a Hydraulic Setting Tool, while retrieval is seamlessly managed independently via a unique Retrieving Tool on a specialized work string. It stands as the ultimate choice for both onshore and offshore applications in highly deviated wells.
Features/Benefits
- Experience the versatility of our retrievable packer-engineered to withstand tie-back, high circulation, rotational torque, and significant reciprocating loads, expertly managing complex well conditions.
- Boasting an integral hydraulic setting capacity, it comes equipped with an internally-configured barrier module to avert any premature setting and hanging issues caused by circulating pressures.
- A distinct feature of our packer ensures it remains unset amidst bumps, friction, torque rotations, heavy tonnage reciprocation, and high circulation. It offers outstanding performance and anti-risk capabilities, promoting safe operations at speeds up to 30m/min.
- Our packers conquer extreme conditions with a maximum dogleg severity through casing exceeding 20°/30m and can be activated beyond 100°, optimizing operational flexibility.
- Optimize well cleanup with robust circulation rates-achieving a 9-5/8" packer cleanup rate of about 6 BPM in field operations, while high circulating pressures ensure the packer remains unset without ball drop.
- Enhanced by dual high-performance packing elements, the packer boasts special materials offering superior sealing abilities against acids, alkalis, oil, high temperatures, and pressures.
- Featuring a specialized sealing and rubber cylinder protection mechanism on either side, this device provides robust strength and ductility, safeguarding the rubber cylinder and ensuring a high load-bearing capacity.
- Utilize both hydraulic and mechanical release methods for service tools. With an inner string tubing swivel head, it guarantees low torque and dependable functionality.
- Crafted from high-strength premium materials, this packer is built to endure significant loads with exceptional durability.
- Working Principle of Top Packer
Initiate setting by dropping a setting ball and filling the string with completion fluid. Apply hole pressure to sequentially shear pins, prompting the upper gauge ring to activate a specialized locking mechanism. The rubber cylinder then undergoes radial elastic deformation, achieving successful setting.
During radial expansion, the rubber cylinder experiences axial displacement. Upon shearing the retainer ring's pin, the slip cage and upper cone advance, with the lower cone anchored, thereby activating and extending the slip, leading to the packer's setting. Post string bleed-off, the check ring secures the components in their set position.
Service Tool Working Principle
Deploy the top packer alongside the sand-control string. Set it by dropping a ball into the drill pipe, activating an internal shield module and piston. The packer is then freed through hydraulic or mechanical reverse release, with the packer service tool retrieved post-completion.
Retrieving Principle
To retrieve the packer, employ a specialized retrievable tool to access the top packer. Once positioned, elevate the tool to shear the support sleeve's pin, while an elastic claw engages with the packer's left-hand thread, allowing for the elegant retrieval of the packer.
