Abstract:
The rheology of oil well cement (OWC) slurries is generally more complicated than that of conventional cement paste. In order to contend with bottom hole conditions, a number of additives are usually used in the OWC slurries. The objective of this research is to develop a fundamental understanding of the important mechanisms that affect the properties of OWC slurry such as rheological properties, free water, compressive strength and thickening time incorporating various chemical and mineral admixtures. The partial replacement of OWC using different nanoparticle weight percent has been proved to be a promising method. The mechanisms underlying the effects of chemical admixtures on the properties of OWC slurry were investigated at different concentrations using advanced experimental equipment. The compatibility and interactions between the binder and chemical admixtures were explored. Finally, it was shown that using nanoparticles would be beneficial from all aforementioned points of view
