| description | The invention relates to the gas and oil producing industry and can be used in raising liquids from oil, gas and gas condensate wells. The proce ss for raising liquids from wells comprises the steps of periodically lowering a device for raising a liquid into a tubing string and subsequently lifting sa me with a column of liquid above it. Between the lateral surface of the device for raising a liquid and the walls of oil well tubings is maintained a ring-shaped gap o f constant width, while a lifting operation is carried out at definite speed when some of the gas from the well will pass through the ring-shaped gap from bottom to top thus preventing the liquid from flowing downwards. The device for raising liquids from wells includes a hoist with a cable, a tubing string and an assembly for raising a liquid placed inside the string with a non-return valve fitted with centralizers and securely fastened to the said hoist. |
