EMULSION COMPOSITION FOR KILLING GAS, GAS CONDENSATE, AND OIL WELLS Russian patent published in 2003 - IPC

Abstract RU 2213762 C1

FIELD: oil and gas production. SUBSTANCE: composition contains, wt %: gas condensate 25.0-30.0, emulsifier (called Emultal) 4.5-5.0, aluminosilicate microspheres as filler 15.0-20.0, waterproofing organosilicon liquid as thermal stabilizer (additional component) 2.5-3.0, and mineralized water 42.0-53.0. Composition exhibits high heat resistance, especially under abnormally low formation pressures, thanks to increased viscosity, improved structural and mechanical properties, thixotropic structure, and reduced filtration to zero values at normal temperatures (at 80 C, filtration is no higher than 4 cu.cm/30 min). EFFECT: improved working characteristics. 2 tbl
