The liner cementing is realized by the liner hanger, which reduces the casing weight of the first well in the deep well, improves the load of the rig lifting system when the casing is cut, and reduces the flow resistance of the cement slurry, which is beneficial to safe construction. Through the liner connection, the problem of drilling operation due to the wear of the upper casing can be solved; using the liner suspension cementing technology can also reduce the amount of casing and save the drilling cost.
