| description | There is provided aqueous fluids comprising a mixture of at least two polysaccharides, water, and glass microspheres having pacified surfaces. There is also provided a method for making a fluid the method comprising (a) selecting a plurality of glass microspheres having alkaline surfaces; (b) coating the surfaces of the plurality of glass microspheres with an acid; and (c) combining the coated glass microspheres with (i) a mixture comprising at least two cross-linkable polysaccharides, and (ii) water. The fluids are useful, for example, as a drilling fluid.
L'invention porte sur des fluides aqueux comprenant un mélange d'au moins deux polysaccharides, d'eau et de microsphères de verre ayant des surfaces opacifiées. L'invention porte également sur un procédé pour la fabrication d'un fluide, le procédé comprenant (a) la sélection d'une pluralité de microsphères de verre ayant des surfaces alcalines ; (b) le revêtement des surfaces d'une pluralité de microsphères de verre avec un acide ; et (c) la combinaison des microsphères de verre revêtues avec (i) un mélange comprenant au moins deux polysaccharides réticulables et (ii) de l'eau. Les fluides sont utiles, par exemple, comme fluide de forage. |
