Abstract
The article considers topical problems of construction and operation of oil and gas wells; issues of cracks in the cement stone in the process of perforation of the casing string. Chemical and physical methods of influence on the plugging solution to improve the quality of the well casing are investigated and applied. The technique of application of chemical reagents, including cationic surfactants in composite plugging suspensions has been developed. Recommendations are given for perforating operations, at which the deleterious effect of thermomechanical loads on the well support is minimized.
