SLURRY FOR HYDROCARBON PRODUCTION AND WATER INJECTION WELL CEMENTING, AND PROCEDURES TO CEMENT WELLS USING SUCH SLURRY

摘要

A slurry for hydrocarbon production and water injection well cementing, andprocedures to cement wells using such slurry are provided. The slurry containsatleast cement and water, and at least an amount of fibers in a ratio of 0.1 to0.8% inweight with respect to cement weight, where the fibers may in general be ofpolypropylene, polystyrene, carbon, alkali-resistant glass, cellulose orpolymers. Theslurry may also comprise other additives, such as dispersants, fluid lossagents,accelerators and retarders, chemical extenders and latex, among others.Procedures tocement hydrocarbon production wells or water injection wells are alsodescribed,where the cement slurry is prepared incorporating fibers into the slurryseparately ormixing them with the remaining dry components before adding water.
