Briefly Introduce:  

The HP retrievable packer/CHAMP Packer is improved from RTTS Packer. Compared with RTTS Packer,the CHAMP IV Packer has a concentric bypass. The CHAMP IV Packer has the capability of circulating below the packer and other parts have the same function as RTTS Packer.

The CHAMP IV Packer is a hookwall-type retrievable packer with concentric bypass. While going in the hole, the bypass is held open until slips are set by the J-Slot that controls the mechanical slips. The bypass is held closed by a balancing piston, which uses work-string pressure to place a downward force on the balancing coupling to prevent the bypass from being pumped open.

structure features

Each assembled tool includes the following components:

J-Slot mechanism

Mechanical Slips

Packer Element.

Hydraulic slips.

Bypass-Round, piston-type slips are used in the hydraulic hold-down mechanism to help prevent the tool from being pumped up the hole. The bypass allows all pumped fluids to flow around the bottom end of the tool. This design prevents the conventional bypass from accidentality opening during circulation around the bottom of packer. In addition, circulation in CHAMP IV Packer is not normally interrupted in the packer elements should seal without operator intent.
