Controlled production and injection

摘要

A well production and injection string includes a plurality of spaced apart packers each adapted to seal with a wall of the wellbore. A plurality of flow control devices are provided in the string, distributed between pairs of adjacent packers. The flow control devices are adapted to communicate flow between an interior and an exterior of the string with less restriction to flow from the interior to the exterior of the string than to flow from the exterior to the interior of the string.

1. A well production and injection string for use in a wellbore, the string comprising:
a plurality of spaced apart flow control devices distributed substantially along a production/injection interval of the string within the wellbore, the wellbore extending from a terranean surface into a target subterranean zone and wherein the portion of the string in the target subterranean zone defines the production/injection interval, the plurality of flow control devices adapted to communicate flow between an interior and an exterior of the string with less restriction to flow from the interior to the exterior of the string than to flow from the exterior to the interior of the string, and wherein the restriction to flow of the flow control devices comprises a fluid diode based valve that accounts for different fluid material properties of injection fluids and production fluids.
