Packer Series
Packer Series
Structure and principle:
Y241 series packer is mainly composed of five major parts: seating mechanism, sealing assembly, anchoring mechanism, locking mechanism and unsealing mechanism, which is a kind of hydraulic packer with novel structure and reliable seating and unsealing performance.
During construction, lower the tool to the sealing position as required, lift the pipe 70-90mm, pressurize 5-8Mpa, lower the pipe column until all the suspended weight is released, pressurize 15-20MPa, stabilize the pressure for 15 minutes, then the sealer cylinder will act, push the casing and rubber cylinder upward, the casing will be stuck in the casing, the sealer rubber cylinder will seal the circumferential space, meanwhile, the hydraulic anchor will extend the anchor claw under the action of hydraulic pressure to realize anchoring and seating. Sealing.
This can be achieved by adding hydraulic pressure to the annulus of the sleeve when backwashing the well.
Unsealing: The tube can be unsealed by lifting up the tube column.
