Downhole screen with exterior bypass tubes and fluid interconnections at tubular joints therefore

摘要

An assembly of screens made of connected joints with exterior bypasses that span the threaded connections among the joints features common fluid connections for the bypasses adjacent joint threaded ends that are connected with a coupling. A mandrel spans from one joint to the next inside the threaded coupling and is sealed to the respective bases pipes on opposed ends of the coupling. At each end of the mandrel the surrounding base pipe has openings from the common fluid connection where the bypasses terminate to define an annular flow path between pairs of common fluid connections. The bypasses can have slanted gravel outlet passages or no gravel openings at all. The bypasses can span over screen or blank pipe with an option to mount a shroud over the generally parallel bypasses.

主权项

1. A completion assembly for subterranean use, comprising:
at least a first and a second tubulars selectively connected with at least one coupling; at least one bypass tube on an outer surface of said first tubular that has ends terminating in at least one first common fluid connection that defines a first annularly shaped path with said first tubular; at least one bypass tube on an outer surface of said second tubular that has ends terminating in at least one second common fluid connection that defines a second annularly shaped path with said second tubular; said first tubular having at least one wall port within said first common fluid connection; said second tubular having at least one wall port within said second common fluid connection; a mandrel mounted within said coupling and defining an annularly shaped flowpath therebetween that puts said first and second annularly shaped paths in fluid communication through said wall ports.
