Carbon additives for high-quality well cementing

Abstract

This article deals with the possibility of adding carbon materials to the cement system. The obtained experimental results are able to analyze the physical and mechanical properties of the grouting mixtures modified with the graphite and its derivatives. The solution of the highly efficient well cementing and fixing operations should be done by the introduction chemical additives to the cement slurry. It is necessary to conduct laboratory investigation with respect to the certain geological, technical and technological features of the mine. That is why several types of carbon additives were examined. The results of this study are useful for finding efficient and ecologically friendly resolution and the maximal strength and minimal permeability values of the grouting mixtures, modified with graphite, oxidized graphite, and flacked thermally expanded oxidized graphite.
