POZZOLAN FOR USE IN A CEMENT COMPOSITION HAVING A LOW HEAT OF HYDRATION |
| 摘要 |
A method of cementing in a subterranean formation comprises: introducing a cement composition into a wellbore penetrating the subterranean formation, wherein at least a portion of the subterranean formation has a temperature less than or equal to the freezing point of an aqueous liquid, and wherein the cement composition comprises: (A) cement; (B) water; and (C) a pozzolan, wherein the cement composition has a heat of hydration of less than 50 BTU per pound; and causing or allowing the cement composition to set in the wellbore after the step of introducing. The pozzolan can have a calcium oxide concentration of less than 15% by weight of the pozzolan, and the pozzolan can have a concentration of at least 15% by weight of the cement. Gas hydrates can be present in or adjacent to a portion of the well. |
