发明名称 Method for determining absolute density of cement slurry
摘要 A method for determining absolute density of a slurry that typically contains entrained air, such as cement slurry, in a continuous mixing operation such those used in cementing a gas or oil well. The method obtains density measurements of a slurry at two different pressures and then uses the two density measurements and the two pressure measurements to compute absolute density of the slurry employing the following formula at isothermal conditions: Dabs=D1/(1-((D1/D2-1)/(P1/P2-1))), where Dabs=absolute density, D1=first density, D2=second density, P1=absolute pressure at which the first density was measured, and P2=absolute pressure at which the second density was measured.
