GRAVEL PACKING SCREEN JOINTS

摘要

A technique facilitates formation of a gravel pack. Gravel slurry is delivered downhole at least in part along a transport conduit from one screen joint to the next. Downstream of a joint connection between two adjacent screen joints, gravel slurry from the transport conduit flows into a gravel slurry chamber. From the gravel slurry chamber, the gravel slurry flows into at least one packing conduit or into at least one packing conduit and at least one transport conduit. The packing conduits are used to discharge the gravel slurry for formation of a gravel pack in a wellbore annulus surrounding the gravel packing system, and the transport conduits are used to deliver the gravel slurry to downstream screen joints for discharge at a more distant location along the wellbore.

主权项

1. A system for use in a well, comprising:
a gravel packing system deployed in a wellbore and comprising:
a pair of screen joints coupled at a screen joint connection, each screen joint comprising a base pipe, a screen surrounding the base pipe, and a conduit extending along the screen externally of the base pipe to deliver a gravel slurry, the screen joint connection coupling the base pipe and the conduit from a first screen joint to a second screen joint of the pair of screen joints;the second screen joint having an annular chamber disposed externally of the base pipe and downstream of the screen joint connection, the annular chamber receiving gravel slurry from the conduit of the second screen joint and distributing the gravel slurry to a plurality of downstream conduits disposed along the second screen joint.
