IntroductionIntroductionIntroduction
The SSTP Retrievable Sealbore Packer is a cutting-edge, versatile Retrievable Packer that is hydraulically set by pressure within the tubing. Its deployment involves a Hydraulic Setting Tool, while retrieval is effortlessly managed independently from the Tubing, utilizing a Retrieving Tool operated on a work string. This innovative packer is exceptionally well-suited for highly deviated wells, whether onshore or offshore, ensuring maximum efficiency and reliability.
Features/Benefits
- The packer offers a wealth of features, including retrievability, tie-back capability, and large circulation. It can be rotated at high torque and reciprocated with substantial loads, adeptly handling numerous complex conditions. This makes it an indispensable tool in challenging applications.
- With an integral hydraulic setting capacity, the internally-configured barrier module serves to prevent premature setting and hanging, which could be induced by circulating pressure. This ensures precise and reliable operations.
- The packer's specialized device ensures it remains unset when encountering bumps, friction, high-torque rotations, large tonnage reciprocation, and extensive circulation. It boasts superior working performance and anti-risk capabilities, guaranteeing a safe running speed that achieves an impressive ≥30m/min.
- With a maximum dogleg severity through casing exceeding 20°/30m, and capable of setting at angles of 100° or more, this packer is designed to conquer the challenges of directional drilling with unprecedented ease and efficiency.
- It enables powerful well clean-up with extensive circulation. In field operations, the 9-5/8" packer achieves a cleanup rate of approximately 6 BPM, without setting issues caused by high circulating pressure, ensuring seamless operations.
- Employing two high-performance packing elements, crafted from special materials, this packer excels in sealing performance. It offers exceptional resistance to acidic, alkaline, oil, high temperature, and high pressure environments, ensuring longevity and reliability.
- The special sealing and robust rubber cylinder protection mechanisms on both sides ensure heightened strength and ductility, fully safeguarding the rubber cylinder. This guarantees a high bearing capacity, even under substantial loads.
- Featuring both hydraulic and mechanical release methods for service tools, and an inner string-installed tubing swivel head, it minimizes operational torque while assuring reliable functionality.
- Made from high-strength premium materials, the packer demonstrates exceptional loading capacity, standing as a testament to its robustness and dependability in demanding applications.
- Working principle of top packer
The process begins with dropping a setting ball and filling the string with completion fluid, applying hole pressure to sequentially shear out corresponding pins. This activates the upper gauge ring's movement, unlocking a unique locking mechanism. Consequently, the rubber cylinder undergoes squeezing, resulting in radial elastic deformation to achieve setting.
During radial expansion, the rubber cylinder also experiences axial displacement. As the retainer ring's shear pin is cut, the slip cage and upper cone are propelled into motion. The lower cone, being fixed, allows the upper and lower cones to move towards each other. This activates the slip, extending it, and achieving packer setting. Post bleed-off, the check ring secures the component, ensuring it remains steadfastly set.
Service tool working principle
Deployed alongside the sand-control string, the top packer is set by dropping a ball into the drill pipe, thus opening the built-in shield module and activating the piston. Release of the packer is achieved hydraulically or mechanically, and the packer service tool is subsequently retrieved upon task completion.
Retrieving principle
For packer retrieval, a special retrievable tool is introduced to access the top packer. Upon reaching position, the retrievable tool is lifted to shear the support sleeve's pin. Concurrently, its elastic claw engages with the left-hand thread on the packer body, allowing for the drilling tool to be lifted and the packer efficiently retrieved.
