Effect of Temperature and Pressure on Rheological Measurements of Cement Slurries
The rheological properties of well cement slurries subjected to elevated pressure and temperature were investigated using a rheometer equipped with a pressure cell and a temperature control mechanism. Simultaneous measurements were performed at ambient conditions for comparison purposes. Two different cement types were included in the investigation, as were three different water cement ratios. Extreme pressure was found to have a negligible effect on workability loss compared to elevated temperature. The effect of particle migration is pronounced in the measurements of mixes at high temperature and pressure.
