METHOD OF GAS-LIFT OIL PRODUCTION WITH AUTOMATIC CONTROL OF WELL PRODUCTION POTENTIALITIES Russian patent published in 2003 - IPC

FIELD: oil and gas producing industry; applicable in oil production. SUBSTANCE: method includes location on tubing string of nipple- funnel, packer, downhole chambers with valves and pressure controllers, bath in oil and gas-supplying wells, and well operation, proper. Nipple-funnel in tubing string of gas-producing well is provided with gas pressure controller maintaining constant pressure in well after itself and over gas supply entire system. The latter is made with same diameters of flow areas up to point of gas introduction into oil well and without throttling units including point of gas introduction into oil well tubing. Working gas-lift valve in point of gas introduction is adjusted so that it opens and by-passes gas only at attained preset pressure of fluid column in point of its installation, but at lower gas pressure in same point of well annular space. EFFECT: reduced expenditures for operation with saving of gas resource of gas-producing well. 2 cl, 1 dwg
