摘要： A method of cementing a wellbore comprises combining a liquid additive with a cement slurry, the liquid additive comprising a metal gluconate, an alkali metal or an alkaline earth metal salt, an alkanolamine, a dispersant, and water to form a cementing composition; injecting the cementing composition into the wellbore; and allowing the cementing composition to set.

摘要： A method of cementing a wellbore penetrating a subterranean formation, the method comprising: injecting into the wellbore an oil-based fluid; injecting into the wellbore a cement spacer fluid comprising an aqueous carrier, an oil swellable elastomer, and a viscosifier; contacting the oil-based fluid with the cement spacer fluid to swell the oil swellable elastomer in the cement spacer fluid; injecting a cement slurry into the wellbore; and allowing the cement slurry to set.
