Abstract

Considering high watercut of the wellstream, the development and selection of efficient cement slurry designs for water shutoff jobs is one of the priorities in oil industry. The cost efficiency of water shutoff depends on the strength properties of the injected cement systems. The paper focuses on gypsum binder-based compositions comprising hemihydrate of calcium sulfate or anhydrite. The authors present description and production process of the compositions, analysis of the temperature effect on the change of properties, results of laboratory studies aimed to determine time of setting of the compositions’ constituents, the effect of water- and hemihydrate of calcium sulfate-based retarders.

Key words:

cement slurry, hemihydrate of calcium sulfate, calcium sulfate dihydrate, anhydrite, optimal cement design, water shutoff jobs, filler-binding cement, time of setting
