RU94028842A - Method for keeping multiple gas wells in production, and ejecting device for implementing the same - Google Patents

Abstract

FIELD: gas production. SUBSTANCE: method lies in the fact that flow rate is redistributed between wells of high discharge and low discharge by creating additional depression in well bottom of low-discharge well at the expense of excessive pressure in high-discharge well. In so doing when varying pressure at gas collector using ejector pressure drop is self adjusted in each well. Ejecting device includes active nozzle, inlet chamber with tangential inlet pipe, diverging and intermediate cavities, mixing chamber and diffuser. EFFECT: improved gas removal. 3 cl, 2 dwg

Claims (1)

The invention relates to the gas industry, in particular to methods for intensifying the selection of gas from a well. The method consists in the fact that the gas flow is redistributed between the high-rate and low-rate wells by creating additional depression on the bottom of the low-rate well due to the overpressure of the high-rate well, and when the pressure at the gas collection point is changed using an ejector, pressure drops in each well are self-adjusting. The implementation of the method is carried out using an ejection device, including an active nozzle, a receiving chamber with a tangential entrance from the loop, a confuser and an intermediate cavity, a mixing chamber and a diffuser. 1 s.p. of f-ly, 2 s.p. of f-ly, 2 ill.
