Apparatus and method for gravel packing an interval of a wellbore
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.
