Disclosed are wellbore flow control devices that allow on-site field adjustments to flow characteristics. One autonomous inflow control device (AICD) assembly includes a base pipe defining one or more flow ports and an interior, a first end ring and a second end ring each arranged about the base pipe, the second end ring being axially-offset from the first end ring such that a fluid compartment is defined therebetween, an AICD arranged within the fluid compartment and having at least one fluid inlet and an outlet configured to be in fluid communication with one of the one or more flow ports, and a flow ring arranged about the base pipe and in fluid communication with the AICD, the flow ring being operable to regulate a fluid flow into the interior of the base pipe and being accessible and manipulatable by a well operator on-site.

Flow rings for regulating flow in autonomous inflow control device assemblies

A bypass assembly for use in a downhole tool comprises a chamber, a first fluid port in fluid communication with the chamber, a second fluid port in fluid communication with the chamber, a flow restrictor disposed in a first flow path between the first fluid port and the second fluid port, a piston moveable in a first direction by the application of a first fluid pressure, a biasing member, and a restraining member disposed adjacent to the piston. The biasing member biases the piston to move in a second direction opposite the first direction, and the restraining member is actuated by movement of the piston in the first direction in response to a predetermined fluid pressure. Movement of the piston in the second direction to a predetermined position configures the bypass assembly to divert fluid flow around the flow restrictor along a second flow path.
