Abstract
FIELD: drilling of boreholes. SUBSTANCE: clay powder contains (in wt %): bentonite clay 94.0- 99.25,, magnesium oxide 0.25-3.0, and sodium carbonate 0.5-3.0. To prepare clay suspension, lump clay with humidity 25% is crushed, dried to humidity 8-10%, ground in disc mill for 20 min and mixed with 13 g of sodium carbonate and 13 g of magnesium oxide. EFFECT: increased yield of drilling mud and reduced its plasticity coefficient. 4 tbl
