The K344 packer is an expandable packer designed for hydraulic setting, pressure relief, and release, suitable for operations such as layered fracturing, acidification, water injection, and channeling. After the construction is completed, release the pressure inside the oil pipe and retract the rubber cylinder to unseal and remove the tool. It needs to be used in conjunction with tools such as aperture reducers and necking tubes.

Features/Advantages

Hydraulic sealing, can be released by releasing pressure, easy to operate

There is no central tube movement during the sealing process, which is suitable for the combination of multi-stage packers

In case of pressure relief or backwashing that cannot be unsealed, the seal can be forcibly lifted up to prevent the pipe column from getting stuck

● Can withstand up to 70MPa (10000psi)

The recommended temperature for conventional rubber cylinders and seals is within 120 ℃
