Abstract:

The hydration rate of Class G net oil-well cement slurry and the slurry with retarder tartaric arid is measured respectively by the meth ods of electricai conductance and acidity, and then the retardation mechanis of tartaric acid is discussed.Experiment results show that the method of electrical conductance can illustrate the hydration prcccss of oil一well cement more thoroughly and mere really than that of acidity.

Key words: Oil-well cement, cement, Retarder, D termintaion, Hycration rate
