The regulation of cement slurry gravities under the factor of sedimentary resistance
E.M.SuleymanovIn the article is defined that Garadagh plant sedimentary resistant slurry made from portland cement corresponds to -0.55 water cement factor. The slurries with higher level of water-cement factor are not so resistant. It is possible to increase the slurry sedimentary resistance for well cementing not losing its usability and increasing water content and in the result decreasing its density. It is determined that water intensity of sedimentary water compartment sharply relieves at viscosity of fluid more than 20 мPа.с and the shear stress slurry in an hour is not less than 60 Pa.
