Description:

The packer is the underhole packoff tool and the compress packer which the support is combined with the hydraulic setting, it depends on hydraulic setting and lising tube to solute seal. It can demonstrate the work principle and the structure composition, and may carry on disassemble and assemble training and the column assembling according to the standard. Setting: After the tool goes down the design position, add the hydraulic pressure from the oil tube, the hydraulic oil affects on the piston through the liquid exit of the upper central tube, after releasing the pressure the hydraulic force drives the piston up and the core pin is sheared, compress the rubber tube to cause it expending the seal oil ring space, the cavain in the piston set locks tightly with the clamped ring to prevent the packer snapping back and realize setting. Solution seal: List the tube, the rpper central tube goes up relatively to the hanger, the dog segment is extruded, the rubber tube is snapping and realizes solution seal.
