FIELD: hydrocarbon production.
SUBSTANCE: invention can be applied to the operation of wells, in particular to equalize the fluid inflow profile along the length of a horizontal well. The fluid inflow control device in the well includes a body containing a main and a secondary channel with flow restrictors, throttle packages, an actuator containing a piston and a shutter, a pressure sensor, and an electromagnetic valve. The device is a prefabricated structure, in the form of a main part with seats for flow restrictors, throttle packages, an actuator assembly, a pressure sensor, an electromagnetic valve and two plugs to ensure that the structure is closed at the ends. Throttle packs containing washers for pressure drop control are made as prefabricated structures, consisting of a body with an external thread at one end for installation in the body of an inflow control device and an internal thread for a threaded nut at the other end. The actuator includes a damper following the profile of the main channel and having a threaded hole for the piston rod and a piston with an internal hole for the rod on one side, and turnkey recesses for assembling the actuator and a rod serving as a guide for the spring on the other side. The threaded bushing limits the damper stroke and is made with a hole for the piston rod and turnkey recesses for assembling the actuator.
EFFECT: limiting the flow of unwanted liquid or gas through the control device and the ability to adjust the pressure drop in the channel network from the wellhead.
