FIELD: oil and gas industry.
SUBSTANCE: device contains the cylindrical housing with two interconnected chambers, one of which contains pressurized gas, and the second one is implemented with a dosing hole and filled with inhibitor. Chambers are divided by a partition, perpendicular to the housing axis, and connected to each other by the device for pressure decrease which is built into the partition and fitted with a tube. One end of the tube is immersed into inhibitor.
EFFECT: reliability of operation of the device, long uniform supply of inhibitor into the formation fluid are provided.
