The liner cementing is realized by the hydraulic rotary liner hanger, which reduces the casing weight of the deep well for one run, improves the load of the drilling rig lifting system when running the casing, and reduces the flow resistance of the injection and replacement cement slurry, which is conducive to safe construction. By connecting the liner, the problem of affecting drilling operations due to the wear of the upper casing can be solved; the use of liner suspension cementing technology can also reduce the amount of casing and save drilling costs.

Features of the Hydraulic Rotary Liner Hanger:
1. The hydraulic rotary liner hanger is made of high-quality alloy steel, with high mechanical strength and heavy suspension tail pipe;
2. The hydraulic rotary liner hanger adopts embedded slips, which can effectively protect the slips during the downhole process;
3. The hydraulic rotary liner hanger adopts separation cone and high-load thrust bearing, which can realize the rotation of the tail pipe;
4. The mechanical locking mechanism prevents the hanger from hanging in advance during the running process;
5. Both the rubber plug and the locking seat are designed with a locking mechanism, which can prevent back pressure and have good drillability;
6. The core of the sealing box can be lifted with the feeding tool, which saves the time of drilling and removing the core of the sealing box;
