METHODS OF CEMENTING SUBTERRANEAN ZONES WITH CEMENT COMPOSITIONS HAVING ENHANCED COMPRESSIVE STRENGTHS

摘要

Methods of cementing subterranean zones penetrated by well bores using cement compositions having enhanced compressive strengths are provided. A method of the invention basically comprises the steps of preparing or providing a cement composition having enhanced compressive strength upon setting comprising a hydraulic cement, sufficient water to form a slurry and a hydroxyamine compressive strength enhancing additive. Thereafter, the cement composition is placed in a subterranean zone to be cemented and allowed to set into an impermeable solid mass therein.
