CEMENT COMPOSITIONS HAVING FAST SETTING TIMES AND HIGH COMPRESSIVE STRENGTHS

摘要

A method of treating a subterranean formation comprising: introducing a first cement composition into the subterranean formation, wherein the first cement composition comprises: (A) a first aluminate cement; and (B) a base fluid; simultaneously introducing a second cement composition into the subterranean formation, wherein the second cement composition comprises: (A) a second cement consisting of cement or a pozzolan; and (B) a base fluid, wherein at least a portion of the first and second cement compositions mix together after introduction into the subterranean formation to form a mixed cement composition, and wherein at least some of the first and second cement compositions or at least some of the mixed cement composition enters into a highly-permeable area located within the subterranean formation; and allowing the mixed cement composition to set. The base fluid can be an aqueous liquid or a hydrocarbon liquid.
