PX-6 Mechanical Set, Double Grip Packer
Description
The PX-6 Packer is a medium duty packer designed to meet requirements for production, testing, zone isolation and injection.
The PX-6 is a medium pressure 41 MPa (6,000 psi) rated packer (in most sizes) and can be set with a minimum amount of tubing weight and packed off in tension which make it a good choice when shallower depths are encountered. It can also be set using compression if there is enough tubing weight available to properly pack-off the elements. Once set the PX-6 can be left in tension, compression or in neutral and will hold pressure from above or below. Alarge internal bypass reduces swabbing and surging effect during run in and retrieval, and closes when the packer is set. When the packer is released, the bypass opens first, allowing the pressure to equalize before the upper slips are released. The Pinnacle PX-6 also features an upper-slip releasing system that reduces the force required to release the packer. Anon-directional slip is released first, making it easier to release the other slips.
Operation
The PX-6 is run to the required setting depth. With the last tubing movement up, apply a quarter turn to the right at the tool and lower until the packer begins taking tubing weight. Release torque and set down required tubing weight at the packer to close the bypass valve, then pull the necessary tension for element pack-off. The tubing string can now be left in tension, compression or neutral.
With tubing weight on the packer, apply right hand torque. Pick up the tubing string, opening the bypass and equalizing pressure across the packer. Continue picking up to release the elements and lock the PX-6 into the running position. The tool may now be retrieved from the well.
