Cement blends including inert microparticles |
摘要 |
Dry cement blends that include inert microparticles may be used to produce cement slurries with a lower viscosity and a longer aging window. For example, a related method may include providing a cement dry blend comprising a plurality of cement particles and a plurality of inert microparticles, wherein the inert microparticles have an average diameter at least about 3 times smaller than that of the average diameter of the cement particles; mixing water, a set retarding additive, and the cement dry blend to yield a cement slurry; storing the cement slurry; mixing a cement set accelerator into the cement slurry; introducing the cement slurry into a wellbore penetrating a subterranean formation; and allowing the cement slurry to set at a location within the wellbore, the subterranean formation, or both. |
