Abstract
A quick connect liner latch system assembly (QCLL). The QCLL latches each joint of a slick line deployed liner together quickly and easily. This system can set an anchor in an existing well bore at a shallow depth and run a new liner in the well with a slick line unit using the QCLL system. It is a safer operation for the workers and environment and cost savings to the operator. The QCLL has two main sections that are locked together to form the full QCLL. The upper and lowers sections are locked together using a body lock ring. The units are not threaded together, which eliminates the need for a conventional rig for installation. The QCLL is unique because the inside diameter (ID) of the latch can remain large enough to accommodate a standard liner wiper plug for the weight of the liner being run into the well.
