Introduction: The new Dual seal hydraulic packer is a hydraulic overall slip Retrievable Casing Packers. It relies purely hydraulic packer may be one or more together down into the well. It is particularly suitable for mechanical packer and Wireline packer unfit down into the deviated. Packer device without moving the tubing, which makes the well has been in good control of the state. You need to install wellhead tubing is finished before because, in a loop or replace tubing was already sitting packer.
After years of exploration, many old wells appeared casing deformation, corrosion and other conditions, such as the southern part of the tower and the wheel wells Tarim Oilfield, in the job, they would often sit Packers to win the title can not be sealed, resulting in job failure to secure oil production has brought many difficulties. After my company related to technical staff and field experts demonstrated many exchanges, the final design was successful hydraulic packer technology solutions with a double set of sealant cartridges, this program can guarantee two cones can be reliably packer, and as long as there is a group cones can reliably sealed when the entire packer can be reliably sealed, which can effectively solve many old wells due to casing deformation, corrosion and other reasons packer seals and other issues can not win the title.
Features: The new Dual seal hydraulic packer is anchored by a hydraulic system, plastic tube sealing systems, two-way slip anchoring system and hydraulic packer system bodies, connecting structure between the two cones of the project the design of the key. Two cones need to ensure reliable and secure packer can re-opened. As long as there is a set of cones reliable sealing, can guarantee a reliable seal the entire packer. Re-opened when needed tools, put on the string to set the lock to unlock the shear pin cut value system, the pressure applied to the plastic tube on the lift, can make two cones back into place, packer unblocking . |
