Cement compositions and methods utilizing nano-hydraulic cement |
摘要 |
An exemplary method includes introducing a treatment fluid comprising nano-hydraulic cement into a subterranean formation. The treatment fluid may include a drilling fluid, a completion fluid, a stimulation fluid, a well clean-up fluid or a cement composition. Another example method comprises introducing a cement composition comprising nano-hydraulic cement, hydraulic cement, and water into a subterranean formation; and allowing the cementing composition to set in the subterranean formation. An example well treatment fluid comprises nano-hydraulic cement. |

1. A method of primary cementing in a subterranean formation comprising:
introducing a cement composition comprising nano-hydraulic cementitious particles and water into the subterranean formation, wherein the water is present in an amount between about 33% to about 200% of the cement composition, wherein the nano-hydraulic cementitious particles have a mean particle size of between about 20 nanometers to about 100 nanometers, the nano-hydraulic cementitious particles being selected from the group consisting of a Portland cement, a pozzolanic cement, a gypsum cement, a soil cement, a calcium phosphate cement, a high-alumina content cement, a silica cement, a high-alkalinity cement, and any combination thereof; and allowing the cement composition to set in the subterranean formation by reaction of the nano-hydraulic cementitious particles and the hydraulic cement with the water to form a hardened mass in a space between the subterranean formation and a pipe string. |
