摘要： A system is disclosed for communication from an instrument disposed in a wellbore. The system includes a flow diverter selectively operable to conduct fluid flow between a first path along the interior of a housing and a second path along the interior of the housing. The system includes an initiator operatively coupled to the flow diverter to cause selective operation thereof in response to an event.

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： An embodiment of the present invention comprises an apparatus for engaging with an outside diameter of a tubular comprises a device body having an internal surface that defines an internal diameter in a first position and allowing the tubular to pass therethrough and an actuator operable to move the internal surface of the device body from the first position to a second position, the second position defining an internal diameter less than the first position internal diameter. The internal surface of the device body is sized with a predetermined grip length for engaging with the outside diameter of the tubular. The grip length is determined by a function of the outside diameter of the tubular and the coefficient of friction between of the outside diameter of the tubular and the interior surface of the device body and the device body is operable to engage with a tubular having a predetermined range of outside diameters.

摘要： A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.
摘要翻译： 暴露在井中的盐水时的可膨胀的封隔器装置。 尽管盐水浓度有显着的波动，该装置可以溶胀至基本恒定的分布。 因此，由于膨胀不足或过度溶胀引起的封隔器故障的可能性降低。 事实上，封隔器可以用于长期操作或隔离，范围从几周到二十年或更长时间，而不用担心从膨胀不足或过度膨胀的封隔器故障。
