Behaviour of a new material for the oil well cementing. Relations between particle structure and rheological properties; Comportement d'un nouveau materiau pour la cimentation de puits de petrole. Relations entre la structure particulaire et les proprietes rheologiques

Abstract

This work focuses on the control and the characterization of the rheological behaviour of Ultra High Performances Concretes (UHPC) for oil well during the dormant period, in the first moments following malaxation. Cement, sand, silica fume, water and a super-plasticizer were principally used in this study. We sought to control their rheological behaviour with simple macroscopic data, such as dry compactness and diameters of the particles. Viscosity and yield stress measurements were determined with controlled stress or controlled rotational speed viscosimeters, by using parallel plates, concentric cylinders, or a vane. We highlight the experimental difficulties generated by the characterization of such mixtures and describe the precautions to take in order to carry out significant measurements. First, we explain the rheological behaviour by traditional granular interactions, such as wall and loosening effects. These interactions allow to predict dry compactness and the rheological behaviour of certain granular mixtures, whose diameters ratio of two successive classes n-1 and n satisfies D{sub n-1}/D{sub n}<0,2 with D{sub n}>D{sub n-1}. The introduction of another concept, named 'spacing', enabled us to evaluate the viscosity of suspension whose diameters ratio of two successive size ranges are large (D{sub n-1}/D{sub n}>0,2), and to predict the behaviour of hollow mixtures.  More>>

We show moreover that it is possible to lower the viscosity and the yield stress of BUHP, by modifying the granulometric distribution of the components, while preserving the same quantity of water. Finally we highlight the particular action of the silica fume, consisted of welded spherical particles and forming not easily breakable clusters, onto the rheological behaviour of BUHP. (author)}
