摘要:
A flow control apparatus for use in a wellbore comprises a screen, a first inflow control device and a second inflow control device, wherein a fluid inflow path is provided through the screen and from an outer portion to an inner portion of each inflow control device. A method of cleaning a flow control apparatus such as that described above comprises providing in a wellbore a flow control apparatus comprising at least one screen and at least one inflow control device wherein a fluid inflow path is provided through the at least one screen and from an outer portion to an inner portion of the at least one inflow control device, targeting the at least one inflow control device with a treatment fluid and delivering the treatment fluid such that the fluid flows in a reverse direction along the fluid inflow path.
