Packer

Purpose:

This pipe column is equipped with HL344 series fracturing packers and various sandblasters to achieve acidification, fracturing and other construction in any layer or layer.

Working Principle of HL344 Packer:

After the fluid enters the pressure transmission hole of the packer from the oil pipe, the expansion rubber cylinder expands and seals the annular space of the oil seal ring. When backwashing is required, the flushing fluid is pumped into the casing, pushing the flushing piston through the inner and outer center pipe annulus to reach the lower part of the packer to complete the backwashing. Stop the pump and unseal it.
