Additive for retardation of cement slurry at ultrahigh static temperatures in a well, on the basis of a mixture of synthetic polymers.
Application:in oil and gas industry in processes of well cementing in order to increase the period of fluidity and setting of cement slurry, improve its rheological properties.
Recommended consumption: added to the fluid for hydration or mixed to the cement in dry form. The recommended concentration range of the additive is 0.03–0.15% to the mass of dry cement. Concentration should be selected according to a definite formulation and parameters.
