Y441 Type Packer

Y441 Type Packer

Y441 type packer Y441 series packer has bidirectional anchoring function, which is widely used in layered oil testing, oil production, water exploration, and plugging
In water and other processes. Especially suitable for processes with large wellbore inclination and difficulty in setting conventional packers.

Working Principle

After the packer is lowered to the design position, hydraulic pressure of 15-16MPa is added to the oil pipe and stabilized for 5 minutes to set the packer. discharge
After compression, check the sealing inside the casing to confirm whether the sealing is reliable. If using the packer at a single level, slowly lift it up when unsealing
Column, observe the changes in the weight gauge. When the load exceeds the original column suspension weight of 70-80KN and is not unsealed, place the column back beyond the limit
The original suspension weight of the pipe column is about 10KN. Then lift the pipe column up until it is completely unsealed. If used in multiple stages, refer to the unsealing method in the document
Level unsealing method.
