摘要： An apparatus for isolating a first zone from a second zone in a subterranean wellbore. The apparatus includes an outer tubular and an inner tubular disposed within the outer tubular forming an annular flow path therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path that is in fluid communication with the second zone. A sleeve having at least one seal is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path.

摘要： An apparatus (110) and method for treating an interval of a wellbore comprises an outer tubular (112) disposed within the wellbore. A sand control screen (118) is disposed within the outer tubular (112). A treatment fluid passageway (144) is formed between the sand control screen (118) and outer tubular (112). In addition, a production pathway (130) is formed between the sand control screen (118) and outer tubular (112). When the apparatus (110) is in an operable position, the region between the outer tubular (112) and the wellbore serves as a primary path for delivery of a treatment fluid, the production pathway (130) serves as a secondary path for delivery of the treatment fluid if the primary path becomes blocked and the treatment fluid passageway (144) serves as a tertiary path for delivery of the treatment fluid if the primary and secondary paths become blocked.

摘要： A multi zone isolation tool (50) for use in a subterranean wellbore includes a first tubular and a second tubular disposed within the first tubular forming an annular flow path (110a, 110b) therebetween and a central flow path (70a, 80a, 80b) through the second tubular. An annular valving assembly (90, 80) is positioned in the annular flow path (110a, 110b) and a central valving assembly (148, 186) is positioned in the central flow path (70a, 80a, 80b). The central valving assembly (186) is operably coupled to the annular valving assembly (90) such that when the central valving assembly (148, 186) is in a closed position, a pressure variation in the central flow path (70a, 80a, 80b) will operate the annular valving assembly (90, 80) from a closed position to an open position.

摘要： Disclosed is a system for using pressure differential between completion fluid in an oil well and produced fluids to power downhole devices, including instruments and actuators. A conduit is provided bypassing a packer which seals a production string to a well casing. A control system, including a flow valve, allows fluid to flow to an electrical generator as needed to charge an electrical storage device. Downhole electrically operated devices, e.g. a temperature sensor and signal transmitter, draw power from the storage device. Alternatively, fluid may also be directed to hydraulically driven actuators to, for example, operate a production fluid control valve.

摘要： An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular (110), which forms a first annulus with the wellbore, and an inner tubular (114) disposed within the outer tubular (110) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway (190) and an axially extending slurry passageway (194), which is defined between a channel (170) and the inner tubular (114). The outer tubular (110) has outlets (128) that are substantially aligned with outlets (178) of the channel (170). The portions of both the outer and inner tubulars (110, 114) adjacent the production pathway (190) have openings (122, 146). When a fluid slurry containing gravel is injected through the slurry passageway (194), the fluid slurry exits through the outlets (178, 128) leaving gravel in the first annulus, thereby gravel packing the interval.

摘要： An apparatus and method for gravel packing an interval of a wellbore is disclosed. The apparatus comprises an outer tubular (110) forming a first annulus with the wellbore and an inner tubular (114) disposed within the outer tubular (110) forming a second annulus therebetween. The second annulus includes an axially extending slurry passageway (194) and an axially extending production pathway (190). The portion of the outer tubular (110) adjacent the slurry passageway (194) has an outlet (128). The portion of both the outer and inner tubulars (110, 114) adjacent the production pathway (190) has a plurality of openings (122, 146). The slurry passageway (194) is in fluid isolation from the production pathway (190) such that when a fluid slurry containing gravel is injected through the slurry passageway (194), the fluid slurry exits through the outlet (128) leaving gravel in the first annulus, thereby gravel packing the interval.

摘要： An apparatus (60) and method for treating an interval of a wellbore comprises an outer tubular (62) disposed within the wellbore. A sand control screen (92) is disposed within the outer tubular (62). A slurry passageway (88) is formed between the sand control screen (92) and outer tubular (62). In addition, a production pathway (90) is formed between the sand control screen (92) and outer tubular (62). When the apparatus (60) is in an operable position, the region between the outer tubular (62) and the wellbore serves as a primary path for delivery of a fluid slurry, the production pathway (90) serves as a secondary path for delivery of the fluid slurry if the primary path becomes blocked and the slurry passageway (88) serves as a tertiary path for delivery of the fluid slurry if the primary and secondary paths become blocked.
