    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 (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.

    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: In general, a method is provided for completing a subterranean wellbore, and an apparatus for using the method. The method comprises positioning an expandable sand-control device in the wellbore thereby forming an annulus between the sand-control device and the wellbore; depositing a filter media in the annulus; and after the depositing step, radially expanding the sand-control device to decrease the volume of the annulus. The sand control device can be a sand screen or slotted or perforated liner having radially extending passageways in the walls thereof, the passageways designed to substantially prevent movement of the particulate material through the passageways and into the sand-control device. Where a slotted liner is desired, the passageways can be plugged during positioning and later unplugged for production. The filter media is typically a particulate material and can be deposited as a slurry comprising liquid material and particulate material, or as a cement slurry. The step of expanding the sand-control device further includes squeezing at least a portion of the liquid of the slurry through the sand-control device passageways thereby forming a pack in the wellbore annulus. The liquid material can be water-based, oil-based or emulsified and can include gelling agents. Further, the particulate can be resin coated with a delayed activation of the resin. The filter media can also be a foam system. The foam can also include decomposable material which can be decomposed after placement of the foam in the annulus.

Another embodiment of the method and apparatus presented herein comprises positioning a well-completion device into the wellbore, thereby forming an annulus between the well-completion device and the wellbore, the well-completion device having a flexible, permeable membrane sleeve surrounding an expandable sand-control device; and thereafter radially expanding the sand-control device to decrease the volume of the annulus, thereby also expanding the membrane sleeve. The well-completion device can further include a layer of filter media encased between the membrane sleeve and the sand-control device. The filter media may be of any type known in the industry. Preferably, the membrane sleeve, when expanded, substantially fills the annular space extending between the wellbore and the sand-control device by deforming to substantially contour the wellbore.
