Beschreibung
Zusammenfassung:	oil- and gas-producing industry; applicable in drilling, completion and killing of wells. SUBSTANCE: light-weight invert dispersion contains hydrocarbon fluid, water and aluminosilicate microspheres and added oil- and water-soluble surfactant, and aluminosilicate microspheres are preliminarily hydrophobized with said surfactant. Light-weight inert dispersion comprises the following ratio of components, mas.%: hydrocarbon fluid, 20.0-52.0; aluminosilicate microspheres, 2.0-30.0; said surfactant, 0.5-3.0; water, the balance. EFFECT: improved quality. 1 tbl, 1 ex
