Well packer
1.oil well downhole tool
2.mechanical packer for plugging
Product Description
1. Scope of application:
Y445packer is mainly used for oil and gas Wells to plug the water layer, so as to complete the stratified oil and gas production of oil and gas Wells
2. Structure and Principle:
1). The double-cone bidirectional slip anchoring mechanism is adopted, which has the characteristics of reliable anchoring and large load bearing.
2). The horse tooth ring locking mechanism is used, which is convenient and reliable to lock.
3). Adopt three-tooth block, automatic aligning anchoring mechanism.
4). Small setting load, high pressure capacity, can withstand 35Mpa upper pressure difference.

Working principle
After the hydraulic pressure is added from the oil pipe and the liquid pressure is passed into the fluid cylinder of the packer, the lower piston is pushed to open the slip and anchor on the casing. At the same time, the lock block of the upper piston is released. At this time, the liquid pressure pushes the upper piston to compress the packer upward, seal the oil jacket annulus, and the locking mechanism is locked after pressure relief to prevent the packer from springback. The design of the setting balancing mechanism can balance the force of the center pipe and prevent the relative displacement of the inner and outer .
