FLOW RESTRICTOR FOR A SERVICE TOOL

摘要

A system, apparatus, and method for gravel packing a wellbore are provided. The system includes a service tool extending through a packer that isolates a proximal annulus of the wellbore from a distal annulus thereof. The service tool defines an inner bore and a conduit, with the conduit being in fluid communication with the proximal annulus and the distal annulus. The system also includes a flow restrictor disposed in the conduit. The flow restrictor is configured to induce a first pressure drop in fluid flowing through the conduit in a first direction and to induce a second pressure drop in fluid flowing through the conduit in a second direction, with the second pressure drop being greater than the first pressure drop.
