METHOD OF DEVICE FOR PRELIMINARY DISPOSAL OF WATER IN GATHERING SYSTEMS OF OIL PRODUCTION WELLS Russian patent published in 1999 - IPC

FIELD: gas and oil producing industry; separation of well production into gas, oil and water. SUBSTANCE: method provides for more complete degassing of gas-and-liquid mixture; oil-water interface is kept in inclined tube below point of introducing stilling pipe line into inclined tube. Stilling pipe line is rectilinear in shape; its diameter is equal to diameter of inclined tube; it is fitted eccentrically relative to inlet of gas-and-liquid mixture over upper generatrix. This pipe line is additionally provided with gas discharge branch pipe at inlet and is mounted in inclined tube at right angle relative to its plane; angle of inclination relative to level ranges from 4 to 15 deg. EFFECT: improved quality of separation of gas-and-liquid mixture. 3 cl, 1 dwg
