Completion equipment having a plurality of fluid paths for use in a well

摘要

A system for use in a wellbore includes a tubing having an inner bore and flow switcher assembly. The flow switcher assembly including a first conduit coaxial with the tubing inner bore and a second conduit formed annularly around the first conduit. One of the first and second conduits is adapted to carry production fluid flow, and the other one of the first and second conduits is adapted to carry injection fluid flow. The flow switcher assembly includes ports in communication with the first and second conduits to enable cross-over flow. In addition, one or more valves may be provided to control fluid flow through the ports.
