Currently, most of the fields of RUE Production Association Belorusneft are at a late stage of development, which is characterized by a high water cut of well production. One of the main tasks in such conditions is the search for engineering solutions aimed at preventing corrosion of well equipment during oil production. Under the operating conditions of producing wells of the fields of RUE Production Association Belorusneft, well equipment is subject to electrochemical carbon dioxide corrosion [1]; mainly the inner surface of the tubing is subject to corrosion attack. The average rate of local corrosion in the corrosive environments of the oil fields of Belarus is 2–3 mm/a.

The first cases of corrosion damage to production tubing were identified in 2010. Taking into account the high cost of stainless tubing, since 2011, the technology of inhibitory corrosion protection has been successfully implemented in the fields of Belarus by the method of constant dosing of the reagent into the annulus of production wells. The use of inhibitors made it possible to eliminate well failures due to tubing leakage, extend their service life by at least 4 times and reduce the local corrosion rate to 0.1 mm/a. However, an increase in the number of production wells damaged by corrosion caused by water encroachment of the wells, as well as an increase in the cost of reagents for oilfield chemicals require the use of new technological approaches, the search for alternative, economically more profitable solutions.
