Model GR-3D Double Grip Retrievable Casing Packers are used in production, stimulation and testing applications. Their hydraulic hold down is below the pressure equalization valve. They feature a proven three element packing system and a balance sleeve device to assist in keeping the by-pass closed.
Reliable sealing system that can withstand upper and lower pressure differences during operation.
Rocker type Slips.
Balanced piston structure enhances tool stability under pressure.
The automatic J-type device can easily achieve setting and unset, and can be set multiple times after running.
Lift-up oil pipe will firstly open the bypass valve to balance the pressure to ensure the safety of the unsealing operation.
Can withstand higher pressure, 7” and below specifications can withstand up to 50MPa (7000psi) differential pressure.
The recommended operating temperature for conventional gum cover is within 148°C (300°F).
