摘要：
Inflow control devices for sand control screens. A well screen includes a filter portion and at least two flow restrictors configured in series, so that fluid which flows through the filter portion must flow through each of the flow restrictors. At least two tubular flow restrictors may be configured in series, with the flow restrictors being positioned so that fluid which flows through the filter portion must reverse direction twice to flow between the flow restrictors. A method of installing a well screen includes the step of accessing a flow restrictor by removing a portion of an inflow control device of the screen.
