Development and application of a packer-type drilling-free liner hanger... When the tripping ball gets into the seat, the pressure will go up to cut off the hanging control pin and set the hanger; (2) continue to hold the pressure and cut off the ball seat pin to form circulation; (3) trip in the drill pipe to exert pressure on the hanger, back off to release the hanger from the running tool; (4) lower the drill pipe plug upon the completion of cement injection, cut off the releasing control pin of hollow casing plug, and run down further to bump with the bumping assembly; (5) remove the cementing head and connect the kelly driver, hold pressure again, then slowly pull up the drill tools, exert hydraulic pressure on the setting hydraulic cylinder of the packer assembly to cut off the setting control pin and set the packer; and (6) pull up the tools to the flare opening and wash out excessive cement slurry by circulating to realize free drilling of the whole hole...
