Abstract
The article considers a set of laboratory studies to assess the effect of basic salt solutions, salt solutions with additives of surfactant compositions, and hydrocarbon-based solutions on reservoir permeability. According to the results of laboratory studies of the filtration properties of the B10 formation, positive parameters of well damping using hydrocarbon-based solutions and a significant negative effect of water-based solutions on the reservoir's filtration properties were noted. Field tests of hydrocarbon-based solutions based on reverse emulsions as a silencing fluid at eight wells have confirmed the effectiveness of this type of solution. In combination with the geological and technical measures for gas dynamic fracturing at wells, it was possible to achieve an increase in the productivity coefficient of wells from an average of 0.2 m3/day at to 0.78 m3/day at.
