Hydraulic Expandable Casing Packer

External casing packer is connected in the casing pipe, Using hydraulic way blowing up the rubber part of casing packer to finish complete packer. Most applied to absorption well, high pressure well, Multiple pressure formation well completion and other completion process.

Strong adaptability it can be used in a variety of different conditions of oil and gas wells.
The valve system can effectively protect and accurately control the tool safety seat seal.
Cones expansion coefficient may packer large diameter borehole.
High temperature resistance levels, Bear big pressure difference and small residual deformation.
ln combination with other cementing tools to achieve different conditions of cementing well, effective solving to the high pressure, low pressure, leakage, back water, subsidence and other complex oil and gas well cementing problems.
