| Abstract: | The article introduces cement slurry rheological characteristics and the method of determining the main parameters for cement slurry rheological characteristics,and analyses the difference between the rotation type and funnel type of viscometers in measuring plastic viscosity and apparent viscosity of cement slurry,and then the limitation of the funnel type of viscometer is described.The difference between rigidity and yield value is pointed out.Finally through analysis of cement slurry rheological characteristics,the cement slurry filling mechanism is proposed,and the main factors affecting cement slurry are studied. |

| Keywords: | plastic viscosity yield value apparent viscosity rheological characteristics cement slurry filling mechanism |
