Model GJ-A Retrievable Packers adopt bottom slip and hydraulic anchor combined anchoring method. The hydraulic hold down is below the pressure equalization valve. The tool features a proven three element packing system and a hydraulically controlled balance piston designed to keep the by-pass closed when set.
Model GJ-A Retrievable Packers are used in Tubing Conveyed Perforating and Single Trip Production, stimulation, perforating, gravel packing and testing applications.
Set securely in any hardness casing, including premium grades.
Surface controlled combination bypass and equalizing valve.
Reliable sealing system that can withstand upper and lower pressure differences during operation.
Balanced piston structure enhances tool stability under pressure.
The automatic J-type device can easily achieve setting and unsetting, and can be set multiple times after running.
Straight pickup of the tubing will first open the bypass valve and equalize pressure, continued pickup will release the packer and automatically engage the packer in the running position for further operations up or down the hole. Guarantee the security of the unsetting operation.
Can withstand higher pressure, 7” and below specifications can withstand up to 70MPa (10000psi) differential pressure.
The recommended operating temperature for conventional gum cover is within 148°C (300°F), cartridges available up to 204°C (400°F).
Similar to Y521 packer with bypass flow.
