A method for treating clayless wash fluids

Abstract

To increase the heat and salt resistance of a wash fluid, monoethanolamine processed waste of licorice production - grist in a volume of 5-8% by weight, is introduced into it as the disperse phase. The processing of the grist is conducted for 1-2 hours at 20-100/sup 0/C and the volume of the monoethanolamine is 0.05-0.1% by weight. The properties of the washing fluids treated by the grist with the introduction of 20% CaC1/sub 2/ into them were not deteriorated, while complete coagulation was achieved with its introduction into washing fluids on the basis of KMTs. Grist washing liquids do not deteriorate their own properties to a temperature of 200/sup 0/C, do not cause equipment corrosion, are inert to swelling clay rocks and with the introduction of KMTs at a temperature above 130-140/sup 0/C cause insignificant destruction of the reagent which is accompanied by a change in the color of the solutions and a drop in the degree of polymerization and viscosity.
