The purpose of this work is to improve the quality of cementing casing strings under conditions of abnormally high and abnormally low reservoir pressures. The processes of expansion of cement stone behind the casing are considered and the expansion dynamics are assessed.
The scientific novelty of the work consists in establishing the dependence of the rate and magnitude of cement stone expansion on temperature conditions, the concentration of the expanding additive, and inhibitors of the calcium oxide hydration reaction; in determining the dependence of the structural-rheological and mechanical properties of cement slurries and cement stone on the composition and chemical nature of their constituent components; as well as in identifying the dependence of well cementing quality on the type of buffer fluid.
