To increase the effect of acid formation treatment (increase in production/injectivity, an overhaul period, reduction of costs of geological and technical works), the authors suggest using a dynamic impact on the wellbore zone (WZ) by using acid creating the rinsing effect with the help of swab equipment and an acid aggregate when waiting for the acid reaction. The article aims to analyze the potential for the application of dynamic impacts on the WZ. The differences of the technology from other impact methods were studied. The main parameters of the wells before and after the dynamic WZ treatment were determined using three indicators: a fluid flow rate, an oil flow rate and a water cut rate. The economic effect of the technology was compared with the effect of the clay-acid treatment (CAT) technology and complex vibrational depression chemical effects (CVDCE). The technology can be used at other NGDUs in order to improve the profitability of field development.
