The RHR-2 packer is a highly reliable, retrievable hydraulic packer widely used in operations such as production, water injection, acidizing, and fracturing. Featuring a hydraulic setting mechanism, it can be deployed individually or in multiple tandem configurations, making it particularly well-suited for challenging well conditions like highly deviated or horizontal wells. The standard model is rated to withstand pressures up to 70 MPa.
Operation
The upper section connects the tubing string, while the lower section is attached to a packer or similar tool before being run into the well.
After the tubing string is properly seated, drop a ball to pressurize and dislodge the ball seat, completing the packer setting.
Simply lift upward until the release force is reached—then the lock will disengage.
It is recommended to use the upper part of the packer in conjunction with a telescopic pipe or hydraulic anchor.
Advantages
The tubing string remains stationary during seating.
The portion above the cartridge features no sealing ring, reducing the risk of failure.
Upper and lower keyway design, capable of withstanding bidirectional pressure;
The special upper-kava anchoring structure is designed for easy unlocking;
Same inner diameter as the oil pipe.
