摘要：
A tool allows in a single trip advancing the liner while more hole is made until the liner is properly positioned. Slips are actuated into the inside of the liner to grasp it as a swage is released to move to support the liner to the surrounding tubular. With the liner supported in the hole, the running tool can be picked up to test the release feature and then set down again for cementing. The tool is then picked up higher to release a flapper and re-pressurized to set a seal adjacent the support previously engaged by swage operation. The flapper has a rupture disc blown and the tool is removed. The tool has an emergency release.
