▎ 摘  要

NOVELTY - A subterranean formation is cemented which involves providing a cement composition comprising cementitious material, aqueous base fluid, graphene nano-platelets, and a dispersant; introducing the cement composition into a subterranean formation; and allowing the cement composition to set in the subterranean formation. Upon setting, the cement has at least one of enhanced compressive and tensile strength; reduced permeability; restricted penetration of carbon dioxide; and its combinations relative to an equivalent cement without graphene nano-platelets. USE - The method is useful for cementing subterranean formation (claimed). ADVANTAGE - Upon setting, the cement has at least one of enhanced compressive and tensile strength; reduced permeability; restricted penetration of carbon dioxide; and its combinations relative to an equivalent cement without graphene nano-platelets (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a well cement composition comprising cementitious material; aqueous base fluid; graphene nano-platelets; and a dispersant, where upon curing, the cement has enhanced compressive and tensile strength; reduced permeability; restricted penetration of carbon dioxide; and its combinations relative to an equivalent cement without graphene nano-platelets; and (2) a wellbore cementing system comprising an apparatus configured to: provide a cement composition comprising cementitious material, aqueous base fluid, graphene nano-platelets, and a dispersant; introduce the cement composition into a subterranean formation; and allow the cement composition to set in the subterranean formation, where upon setting, the cement has enhanced compressive and tensile strength; reduced permeability; restricted penetration of carbon dioxide; and its combinations relative to an equivalent cement without graphene nano-platelets.
