WELL FLUID TREATMENT METHOD AND DEVICE FOR ITS IMPLEMENTATION IN WHOLE AND ITS PART Russian patent published in 2020 - IPC E21B43/00 E21B43/38 E21B28/00 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to oil industry and can be used, in particular, in mechanized method of oil production for treatment of well fluid by acoustic action. Well fluid treatment method based on acoustic action on well fluid and including arrangement in the well of well fluid treatment device containing at least one tubing string with a pump, consists in placement in well of at least one submersible treatment module of borehole fluid located between tubing and pump. Submerged module is made in the form of shell with inlet and outlet of processed well fluid and contains at least two acoustic resonators arranged in shell coaxially with it, separation chamber of processed well fluid, its output is connected to inputs of acoustic resonators, and its input is to inlet of submersible module, and mixing chamber of processed well fluid, its input is connected to outputs of acoustic resonators and its output is with output of submersible module.

EFFECT: higher efficiency of oil production.
