发明名称 APPARATUS AND METHOD FOR INSTALLING COILED TUBING IN A WELL
摘要 Hanger apparatus for suspending coiled tubing in a well including a tubing head having a vertical flow passage therethrough. An annular sealing assembly is carried in a low counterbored portion of the flow passage. A slip assembly is carried in an upper counterbored portion of the flow passage. The slip assembly is moveable between an outwardly expanded passive position in which the slip assembly does not interfere with the flow passage and an inwardly contracted active position in which gripping surfaces carried on the slip assembly engages the coiled tubing to support the weight thereof, the weight of the tubing being transferred from the slip assembly to the sealing assembly. Slip activators carried by the tubing head are manipulatable externally of the tubing head to move the slip assembly from passive positions to active positions. A method of utilizing the apparatus to install coiled tubing in a well is disclosed.
