Particle transport fluids thickened with acetylate free xanthan heteropolysaccharide biopolymer plus guar gum |
摘要 |
A non-acetylated but otherwise unmodified xanthan heteropolysaccharide polymer plus guar gum, is employed to impart viscosity to an aqueous particle transport fluid (such as a drilling fluid, a fracturing fluid, or a filter structure emplacement fluid) sufficient to suspend mineral particles. A cross linking agent can also be employed to decrease the amounts of xanthan heteropolysaccharide polymer and guar gum which are needed for particle suspension.
