Patent

CA 2522500

The present invention provides cement compositions having enhanced mechanical properties and comprising microspheres and carbon fibers, and methods for cementing in a subterranean formation using such cement compositions. The cement compositions comprise a cement material, carbon fibers, microspheres, sufficient water to form a slurry, and optionally other ingredients including an accelerant, a retardant, a surfactant, or the like.

L'invention concerne des compositions de ciment présentant des propriétés mécaniques améliorées et comprenant des microsphères et des fibres de carbone, ainsi que des procédés de cimentation dans une formation souterraine au moyen desdites compositions de ciment. Ces compositions de ciment comprennent un matériau de ciment, des fibres de carbone, des microsphères, et suffisamment d'eau pour former un lait de ciment, et éventuellement d'autres ingrédients notamment un accélérateur, un retardateur, un tensioactif ou analogues.
