ABSTRACT:
A system for sealing and anchoring reeled tubing in a landing nipple in well tubing. An hydraulically actuated lock mandrel having a locator is connected on the reeled tubing and lowered inside the tubing and into the landing nipple. The lock mandrel sealingly engages the landing nipple and the locator stops downward movement of the lock mandrel in the landing nipple. Pressure applied in the reeled tubing actuates the lock mandrel to lock and anchor the reeled tubing in the landing nipple. On sufficient reduction of pressure in the reeled tubing, the lock mandrel automatically unlocks from the landing nipple. Two embodiments of the lock mandrel are disclosed, each utilizing a different type of locator.
