The Effect of Sample Storage and Inspection Equipment on the Rheological Property of Oil Well Cement

Abstract:

In this research, the influencing factors of oil well cement on the rheological property were experimentally studied. Based on the experiments and surveys of other class G oil well cement plants, the main influencing factors in the routine inspection were sample storage and processing condition and inspection equipment accuracy. The experimental results illustrate that sample storage and processing condition had a highly effect on the rheological property of drilling cement slurry. In addition, temperature positive deviation increased the rate of cement hydration by causing more rapid nucleation of hydration products, leading to earlier thickening time; conversely, minus deviation delayed cement nucleation, causing later thickening time. Compared with temperature deviation, the effect of pressure deviation was not obvious.
