    摘要: A trailer (10) has a dropped center section (12) defining a well (16) for a coiled tubing reel (22). A mast (30) has a pair of posts (34) on which a carriage (32) is mounted for movement along posts (34). An injector head (36) is supported on carriage (32) for pivotal movement in a vertical plane relative to mast (30) and for horizontal movement along a tubular support member (38) of carriage (32) relative to mast (30). Mast (30) is pivotally mounted on the rear end of trailer (10) for movement away from trailer (10) for positioning over a wellhead. In a stored position, mast posts (34) fit alongside the ends of reel (22) so that to the total height of the stored coiled tubing rig is no more than 13½ feet for over the road travel.

    摘要: A levelwind system for a coiled tubing reel (26) including an arcuate guide arm (48) extending over the upper surface of the reel (26). A universal joint (50) mounts the lower end of the arm (48) for pivotal movement both vertically and horizontally. A guide member (52) is supported on the free end of the guide arm (48) for guiding the coiled tubing T on and off reel (26). A lift cylinder (54) is effective to raise and lower guide arm (48). A balancing cylinder (60) is effective for moving guide arm ME (48) laterally. A hydraulic fluid circuit responsive to a position sensor (111) and a microprocessor (112) as shown in FIG. 12 is effective for controlling the movement of the coiled tubing guide arm (48).

    摘要: A pressurized fluid is "let-down" to atmospheric pressure as it passes through a choke assembly having two pressure orifices (choke flow beans) which are in-line and directly opposite and which are designed to deliver jet streams of generally equal force to a common in-line focal point. The choke assembly is a fixed-rate system where the volume throughput is regulated primarily by the pressure on the fluid.
