Abstract RU 2285713 C1

FIELD: well drilling engineering.

SUBSTANCE: invention relates to compositions for grouting cavernous spaces and absorbing beds of wells to reinforce intervals with trend for falls occurring in oil, gas, and mining industries (during construction of impervious barriers) in well drilling operations, including drilling of non-producing technical-destination wells. Grouting composition contains 20-65% mud powder, 0.5-65% water absorbing polymer, and 34-60% vegetable, synthetic, or mineral oil.

EFFECT: improved quality of insulation of absorbing beds at better environmental conditions.
