  • Apparatus and method utilizing a coiled tubing injector for removing or inserting jointed pipe sections
    Patent number: 5975203
    Abstract: Apparatus and method for pulling or inserting jointed pipe sections (18) having upset ends (20) within a well utilizing a coiled tubing injector (26). The coiled tubing injector (26) has a pair of opposed endless chains (50, 52) including gripper blocks (58) for gripping the pipe sections (18). An axial gap (G) is provided in chains (50, 52) between adjacent gripper blocks (58) to receive the upset ends (20). To align accurately upset ends (20) with gap (G), a sensing mechanism (100, FIGS. 11 and 12) is provided to sense the location of upset end (20) and a sensing mechanism (110, 112, FIGS. 13 and 14) is provided to sense the location of gap (G). An operator in response to signals from the sensors accurately aligns upset ends (20) with gap (G).
