ABSTRACT

This research investigates the problem of well cementing in areas with the presence of permafrost. The analysis of the main complications arising from attaching wells under permafrost conditions is carried out, as well as the results, showing an indicator of the adhesion of cement stone with a casing string. The importance of the correct choice of cement material with regard to its thermophysical and technological properties in order to reduce operating problems is emphasized. The results of studies of the influence of micro silica on the structure and properties of cement stone are presented. The expediency of using silicon production wastes to increase stone strength indicators is shown.
