REACTANT FOR TREATMENT OF CLAY-FREE DRILLING MUDS

摘要

FIELD: drilling of boreholes. SUBSTANCE: aim is to increase flocculating features and stability of filtering features of drilling mud against action of drilled out rock with simultaneous preservation of drilling mud high rheological performance objectives and high stability of filtering features against action of polysalted mineralization. Reactant has following ingredients, mass %: polyacrylamide 1.0 - 2.0; magnesium oxide 1.0 - 4.0; lignosulfonate 20 - 25; water - balance. EFFECT: increased flocculating features and drilling mud stability to action drilled out rock. 2 tbl
