Flow-Activated Flow Control Device and Method of Using Same in Wellbores

摘要

A flow control device for use in a wellbore is disclosed that in one non-limiting embodiment may include a main flow passage and a weep hole, wherein the main flow passage closes when a fluid is supplied to a first end of the valve that exceeds a selected rate and opens when the fluid supplied is below the selected rate and wherein the weep hole continues to allow the fluid therethrough.

主权项

1. An apparatus for use in a wellbore, comprising:
a valve body having a first end and a second end, the valve body being movable in the housing, the valve body including a main flow passage that allows a fluid supplied to the first end of the valve body to flow through the main passage into the flow passage in the housing and a weep hole that allows the fluid from the weep hole to enter the valve body, the valve body being biased to attain a first position wherein the fluid supplied to the first end below a threshold rate allows the fluid to pass therethrough and prevents the flow of the fluid through the main flow passage above a threshold rate while allowing the fluid to flow through the weep hole.
