APPARATUS FOR CONNECTING A TOOL STRING TO COILED TUBING IN DOWNHOLE OPERATIONS

摘要

A connection between a downhole tool string and axially extending coiled tubing 102 includes a compression ring 120 that in use grips the coiled tubing sufficiently to enable a slip ring to be set and provides a satisfactory seal with the coiled tubing 102. The compression ring 120 is preferably of a relatively malleable metal and includes a skirt 142 of reduced thickness to be preferentially compressible and which in use is compressed against the coiled tubing 102.
