AQUEOUS CEMENT COMPOSITIONS INCORPORATING PARTICLES THAT ARE ACTIVATED TO CONTROL RHEOLOGY WHEN WATER SOLUBLE PORTIONS OF THE PARTICLES ARE RELEASED IN THE PRESENCE OF WATER |
摘要 |
<p>The present invention provides strategies for improved control of fluid loss, hydration, settling, and separation of aqueous cementing compositions over a wide temperature and time range. The present invention is based at least in part upon water-effusing particles used as additives for the compositions, wherein the particles are activated to control rheology when water soluble portions of the particles are released in the presence of water.</p> |
