Inflow control devices for sand control screens. A well screen includes a
filter portion and at least one flow restrictor configured so that fluid
which flows through the filter portion also flows through the flow
restrictor. The flow restrictor includes at least one tube which forces
the fluid to change momentum within the tube. An inflow control device
for restricting flow into a passage of a tubular string in a wellbore
includes at least one flow restrictor configured so that fluid flows
between the passage and the flow restrictor. The flow restrictor includes
at least one tube which forces the fluid to change momentum within the
tube.
