The present invention provides a cementing composition for an oil or analogous well, essentially constituted by a solid fraction suspended in a liquid medium. The solid fraction is constituted by a coarse fraction with a packing volume fraction .PHI.1 which, according to the invention, is maximised, and a fines fraction x with a packing volume fraction .PHI.2 which is less than or equal to the volume fraction x0 such that x0 = (see fig. I) The invention also provides a method of maximising the value of .PHI.1. The invention can minimise fluid loss whatever the materials selected for a cementing composition.
Cette invention concerne un matériau de cimentation de puits de pétrole ou puits analogue constitué essentiellement d'une fraction solide en suspension dans un liquide. La fraction solide est composée d'une fraction grossière représentant une fraction volumique .PHI.1 qui est maximisée et une fraction fine x représentant une fraction volumique .PHI.2 qui est égale ou inférieure à la fraction volumique x0, la fraction x0 étant égale à (voir fig. 1). L'invention prévoit également une méthode de maximisation de la valeur .PHI.1 pour minimiser la perte de fluide peu importe les matériaux constitutifs choisis.
