Abstract
Well cementing is one of the most important operations performed in an oil well. An adequate rheological characterization of the slurry is r equired to optimize cementing parameters. A study of chemical and micr ostructural development of a cement slurry and its impact on rheometri c behavior was carried out. Scanning electron microscopy, X-ray diffra ction analysis and rotative rheometry were used. Hydration of the slur ry was followed at rest and under shear. It is shown that chemical rea ction kinetics, microstructure development and rheometric behavior dep end markedly on the shear conditions during hydration. (C) 1997 Elsevi er Science Ltd.
