Liners hanger hydraulic double-grip packer double-row casing
Liners hanger hydraulic double-grip packer double-row casing is designed for suspension and sealing of casing section of considerable weight in pre-lowered casing after cementing. When securing casing, it ensures its straightness during setting of cement slurry, thus preventing unloading on cement stone, effectively affecting contact of cement stone with casing and reliable sealing of inter-casing space, making it impossible to overflow formation fluids during drilling operation. Liners hanger PL-LH/HD2G is used for both vertical and directional wells and can be combined with various process equipment.
