Stavychnyy Y. Development of plugging systems for chemical deposits cementing in the wells of Dniepro-Donets Basin fields

The thesis is devoted to the development of plugging systems for chemical deposits cementing in the wells of Dniepro-Donets Basin fields to improve the quality and reliability of well casing. Basic plugging materials have been assessed and plugging systems for chemical deposits cementing have been developed with the help of modern methods of analytical analysis and experimental studies using mathematical modelling methods, research methods, devices and materials. According to the results of practical testing of cementing systems, their technological usability and adaptation for casing cementing contributing to the quality and reliability of well casing in complex geological conditions have been proved.
