The article presents the features of the application and the criterion of the method of hydrochloric acid treatment of the bottomhole zone of wells. The high variability of reservoir properties and low values of formation pressures reduce the efficiency of using conventional hydrochloric acid solutions in carbonate reservoir conditions to a minimum. In the course of treatment, the acid moves mainly along the same channels and cracks, leaving a significant part of the reservoir without impact. To eliminate the factors that reduce the effectiveness of the DIS, a special composition of the ZSK has been developed, which is added to the hydrochloric acid solution and a number of technological solutions for its application.
