INHIBITOR SUPPLY DEVICE Russian patent published in 2017 - IPC E21B37/06 

FIELD: oil and gas industry.

SUBSTANCE: device contains a cylindrical body with a top lid, overlapped on the underside with a bottom with a dosage hole for the inhibitor run-out, located in the body. The body is provided with a hollow tube, one end of which is immersed into the inhibitor, and the second is mounted into the inlet of the top lid and is hydraulically connected to the annular space. An input module is mounted on the top lid, communicating with the hollow tube and preventing formation water from entering the container. The input module is made in the form of a thick-walled cylinder, having a central through-passage and inner axial channels uniformly located around it in a circumferential direction, radial inlet openings, designed under the intake flow divertor and connected to the lower part of the axial channels, wherein the axial channels communicate with the central channel in its upper part by means of inclined connecting grooves.

EFFECT: constant flow rate of the inhibitor without changing its concentration is ensured.
