DEVICE FOR REMOVING LIQUIDS THAT ACCUMULATE IN THE WELL Russian patent published in 2018 - IPC E21B43/12 F04F1/20 

Abstract RU 2671372 C1

FIELD: mining.

SUBSTANCE: group of inventions relates to the apparatus and method for removing fluid from the production well. Device comprises the reservoir (104, 105) having the liquid storage zone (109), the mentioned reservoir is designed with the possibility to be connectable to the gas removal pipe (102), which is located in the production well; the isolator (106), which is designed with possibility to be adapted to restrict the flow of fluid between the reservoir wall (104) and the borehole wall (101) from the first space (107), which is formed between the insulator and the well bottom, into the second space (108), which is formed between the insulator and the wellhead; the first opening (117a), which is formed in the mentioned reservoir with the possibility to circulate a gas-liquid mixture from the mentioned first space to the third space (110), which is formed in the gas removal pipe; and the second opening (116a) in the mentioned reservoir, which is designed with the possibility to be adapted to circulate the fluid from the mentioned second space to the fluid storage zone. First opening is formed between the liquid storage zone and the connection to the removal pipe. Moreover, the reservoir in the storage zone is sealed.

EFFECT: technical result consists in increased efficiency of removing liquids that accumulate in the well.
