Properties of oil-well cements containing calcium sulphates of various nature.

The article presents the findings of studies involving the optimization of the composi­tion and grinding fineness of oil-well cement PTsT100 obtained by using natural and technogenic gypsum-containing components. It was established that, while using gypsum­containing components of various nature in combination with appropriate values of the cement specific area. the standard properties of the pit-well cement could be ensured. It is shown that the impact of calcium sulphates on the cement properties depends not just on their nature but, to a substantial degree. also on the physical charateristics .
