Yielding of Hydrated Lime in Set-Delayed and Other Settable Compositions |
摘要 |
Methods and systems directed to controlling the rheology of settable compositions in subterranean formations. Embodiments include a method of controlling the rheology of a set-delayed cement composition, the method comprising: providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder; shearing the set-delayed cement composition in an amount sufficient to substantially prevent solids settling; storing the set-delayed cement in a pumpable fluid state for at least 1 day; activating the set-delayed cement composition; introducing the set-delayed cement composition into a subterranean formation; and allowing the set-delayed cement composition to set in the subterranean formation. Additional methods and systems are also provided. |
