The object of research is a well and a productive formation. The purpose of the work is to increase the duration of the effect of reducing water cut after treatment of the bottomhole zone of watered wells. In the considered well stock, there is a trend towards an increase in the number of measures to treat the bottomhole zone of water cut wells. At the same time, the analysis of the accumulated experience of activities for the treatment of the bottomhole zone of this category of wells indicates a decrease in water cut after treatments. In this article, for the use of watered wells (90 % or more) in the production fund, an approach is proposed aimed at increasing the duration of the effect of reducing water cut after treatment of the bottomhole zone. It is assumed that the effect will be achieved through the combined treatment of the bottomhole zone, which includes the sequential injection of acid and water-repellent compositions.
