The main task of cementing wells is hermetic separation of rocks with different saturation patterns. The solution to this problem is quite difficult, because it depends on many factors.</p> <p>Based on the analysis of the results of acoustic cement bond logging and field studies of wells, it was found that the quality coefficient of cementing with a slight error can characterize the annulus integrity. In this regard, when conducting skilled or experimental work, the quality coefficient of cementing was used by us as the main parameter for evaluating the effectiveness of various technological operations carried out during well cementing.</p>cementingcementing qualityinfluencing factorsMangystauцементтеуцементтеу сапасының коэффицентіцементтеу сапасына әсер ететін факторларМаңғыстауцементированиекоэффициент качества цементированияфакторы, влияющие на качество цементированияМангистау.1.Nagimov IR, Fatikhov RI, Agzamov FA.
