    摘要: A method of cementing a subterranean formation includes 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 combinations thereof relative to an equivalent cement without graphene nano-platelets. Cement compositions include cementitious material, an aqueous base fluid, graphene nano-platelets, and a dispersant.
