Zusammenfassung:drilling fluids. SUBSTANCE: water-based drilling mud contains, %: polyalkylene glycol, 1-5; clay, 3-15; and stabilization reagent, 0.5-5. The latter can be represented by anionic and nonionic polymers, lignosulfonates and their derivatives. Novelty resides in that polyalkylene glycol is ethylene oxide/propylene oxide copolymer depicted by following structural formula , wherein X is O, N, or CH2; Y is N or CH2; c, a, b =0-2; t, q, g, m, k vary from 0 to 250; d =1-5; R1,R2,R3 are H or methyl; A, B, and G vary from 1 to 120; and 3
