Investigation of factors influencing the process of cement formation and its contacts with casing pipes on the example of Mangystau region fields

Abstract

This work is devoted to the study of factors affecting the formation of cement stone and its contacts with casing pipes, the development of recommendations and technological methods to improve the quality of well cementing. 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.
 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.
