ABSTRACT:
A method of production of the formation fluid is used in wells with a low formation pressure and consists in that in the well from a flow of the formation fluid forcedly liberated is the gas dissolved therein and then the formation fluid is transformed into a finely dispersed gas-liquid flow in which the amount of liberated gas ensures self-lift of the formation fluid to the wellhead. A device, effecting this method, comprises a body hermetically secured in the well string, a nozzle and Venturi tubes. The Venturi tubes are installed over the nozzle, coaxially with it, and each below-positioned tube serves as a nozzle for the above-positioned one.
