Popis:	Well cementing is one of the most important operations performed in an oil well. An adequate rheological characterization of the slurry is required to optimize cementing parameters. A study of chemical and microstructural development of a cement slurry and its impact on rheometric behavior was carried out. Scanning electron microscopy, X-ray diffraction analysis and rotative rheometry were used. Hydration of the slurry was followed at rest and under shear. It is shown that chemical reaction kinetics, microstructure development and rheometric behavior depend markedly on the shear conditions during hydration.
