<p>The invention relates to the production of gas and oil in wells. According to the inventive method, devices are sequentially installed in a tubing, whereby said devices form the stream structure and separate liquid and gas phases. The distance between the devices ensures that the quantity of liquid moved upwards is higher than the quantity of liquid running downwards. In a first embodiment, the devices include a tubing and a displacement chamber which has the form of an inverted cup. The cup can move axially, whereby the travel of the cup is defined and controlled by a formula. In another embodiment, the cup comprises side openings in the lower section thereof and a flange in the top section thereof, whereby said flange normally blocks the gas exhaust openings inside a sleeve. Said sleeve is secured between the ends of the tubing members. The cup flange can move axially along the tubing.</p> |
