FIELD: oil and gas industry.SUBSTANCE: method for extraction of gassy cut and degassed fluid is referred to oil production and it can be used for production of gassy cut and degassed fluid from deep wells. In borehole pump a hermetical ring is made for movement of annular circuit 7 equipped with actuating pistons 8. For this purpose guide pipeline 12 and pipe string 4 are connected from the bottom with one or several operating cylinders 6, input-filtering chamber 10 of borehole pump, leading sheave 9 while from the top they are connected to upper body, hoisting sheave 22, pulling down sheave 23 and stretching pulley 24.EFFECT: continuous lifting of gassy cut and degassed fluid from deep and shallow depth with large content of associated gas from wells with low yield due including without limitation permanent speed of circuit with pistons through operating cylinders which length is more than distance between pistons.2 cl, 5 dwg |
