초록 ▼

There is described a method and apparatus for connecting the end of coiled tubing to a downhole tool string, comprising a first tubular housing having a first uphole and a second downhole end and a bore formed therethrough for a length of coiled tubing, a second tubular housing adapted for releasable connection to the downhole end of the first housing, the second housing having a first uphole and a second downhole end and a bore formed therethrough for receiving the length of coiled tubing at least partially into the second housing, slips adapted to at least partially surround the coiled tubing and having on an inner surface thereof raised projections for penetrating a contiguous surface of the coiled tubing for connection thereto, the slips additionally including connectors to interlock with cooperating connectors on the second housing for a non-rotatable torque transmitting connection therebetween, and a force transmitting member disposed between the slips and the first housing to maintain the slips in compressive contact with the coiled tubing.
