发明名称 EMULSION COMPOSITION FOR KILLING GAS, GAS CONDENSATE, AND OIL WELLS
摘要 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
