The tool is a hydraulic expansion packer

• When the tubing pressure is greater than the casing pressure 0.4-1.2MPa, the rubber cylinder expands and seals the annular space of the oil jacket

• Must be used with the throttle, with good sealing, high pressure resistance, long service life, no stuck pipe column and so on

Usage

The packer is used in combination with other tools such as restrictor and single flow valve for stratified fracturing, stratified acidification, uniform acidification, jet acidification, stratified water injection, casing leak finding, plugging and setting.
