System and method for maintaining operability of a downhole actuator

摘要

Methods and systems for facilitating actuation of downhole components by filtering actuation fluid and by preventing inoperability due to plugging. A well component is deployed downhole into a wellbore and operated via an actuator moved by a flow of fluid. A filter system is mounted in the flow of fluid to remove debris before the flow of fluid reaches the actuator. The filter system further comprises a pressure release member that opens when sufficient pressure builds up due to plugging of the filter system.

主权项

1. A system to facilitate an actuating fluid flow for a well component, comprising:
a formation isolation valve that can be actuated by a flow of fluid; a filter system coupled to the formation isolation valve to filter the flow of fluid during actuation, the filter system comprising a flow passage for conducting the flow of fluid, a filter mounted in the flow passage, and a pressure release member that opens under sufficient pressure to allow continued flow of fluid when the filter becomes plugged, wherein the pressure release member comprises a retention member working in cooperation with the filter to enable the filter to separate from a surrounding housing when exposed to the sufficient pressure; and wherein the pressure release member comprises a ring press fit into the surrounding housing.
