During reservoir development process, the permeability of near wellbore zone decreases, and filtration characteristics of productive formations deteriorate due to anthropogenic impact for the primary and secondary improved oil recovery process and other technological operations. To restore and improve the productivity of wells in heterogeneous low-permeability terrigenous reservoirs, classic acid treatments are recommended. Aggressive secondary sedimentation or in other words, precipitation occurs during acid treatments in terrigenous reservoirs, confirming the effectiveness of putting wells into operation through the proposed chemical composition as the cleaning and stimulating operations. Therefore, a comprehensive approach and methods of impact on the near wellbore zone are necessary, as these are multifactorial processes. This research is focused on developing effective technologies to improve technical means or compositions that restore well productivity by decolmatizing the formation and substantiating effective chemical compositions. The results of this work show that the proposed method and chemical reagent highly improved the permeability of near wellbore zone and as a result increased the productivity index of the well.
