WELLS HIGH INTENSITY ABSORPTION INTERVALS INSULATION METHOD AND AERATED SLURRY FOR ITS EXECUTION

摘要

FIELD: oil-and-gas production.;SUBSTANCE: in a wells high intensity absorption intervals insulation method execute cement slurry pumping, then - a polymer content, at that use an aerated solution as the slurry, with the base, mass p. Portland cement 85-100,alluminium silicate micro spheres up to 15, foam creator - anion SAS base on a resin and naphthene acid basis 0.1-0.3, setting time activator 4.0-7.0, water 50-60, and additionally - gas agent in quantity, providing the mentioned above solution density 800-1000 kg/m³, and a poly-cement paste used as the polymer solution, created by mixing compositions I and II of a defined content. Invention develops in formula subclaime.;EFFECT: insulation works time consumption decrease, creating a reliable insulation in a catastrophic absorption conditions.;6 cl, 1 ex, 2 tbl, 1 dwg
