Cementing compositions for oil wells or the like comprise between 30 % and 100 % (by weight of cement) of rubber particles, with grain size in the 40-60 mesh range. Adding rubber particles in accordance with the invention produces a low density slurry while keeping the cement permeability low. Compositions of the invention are particularly advantageous for cementing zones subjected to extreme dynamic stresses such as perforation zones and the junctions of branches in a multi-sidetrack well.
Selon cette invention, des compositions de cimentation pour puits de pétrole ou similaires comprennent entre 30 % et 100 % (en poids de ciment) de particules de caoutchouc avec une granularité moyenne de l'ordre de 40 à 60 unités de tamisage. L'ajout de particules de caoutchouc selon le procédé de l'invention permet d'obtenir une suspension de faible densité tout en maintenant un faible perméabilité du ciment. Les compositions de l'invention conviennent particulièrement bien pour cimenter des zones soumises à des contraintes dynamiques extrêmes telles que les zones de perforation et les branchements à dérivations multiples.
