METHOD OF WELL COMPLETION |
摘要 |
FIELD: drilling, development and operation of wells of gas, gas-condensate fields; designed for safe performance of jobs involved in well completion. SUBSTANCE: method is realized by compressing of hot exhaust gases of diesel motors by liquid-gas ejector of the first stage of ejection at exhaust temperature. Hot liquid-gas mixture is supplied under pressure to separator. Compressed gas phase is separated and supplied at controlled temperature to liquid-gas ejector of the second stage of ejection for generation of two-phase foam of preset density with reduced gas phase temperature to optimal value. Produced two-phase foam is supplied to well under pressure through tubing. Supplied to flow of foam-gas mixture at outlet of annular space is part of hot exhaust gases from diesel motors for maintaining temperature of formed foam-gas mixture above temperature of foam breaking. EFFECT: higher efficiency of well completion and breaking of used foam into components by supply of hot exhaust gases. 2 dwg |
