Hydraulic double-gripping packer liner hanger
Hydraulic double-gripping packer liner hanger is designed for suspension and sealing of casing string section "liners" in pre-lowered casing string after cementing or without cementing the well. While anchoring casing provides its straightness during cement slurry setting thereby preventing unloading on cement stone, effectively affecting contact of cement stone with casing and reliable sealing of inter-casing space, excluding overflow of formation fluids during well operation. PL-LH/HDG liners hanger is used for both vertical and directional wells and can be combined with various process equipment.
