METHOD FOR PETROLEUM PRODUCTION AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2022 - IPC E21B43/00 

FIELD: petroleum industry.

SUBSTANCE: invention relates to the petroleum industry and can be used in the operation of production flowing and mechanised boreholes. Claimed is a method for petroleum production including lifting the downhole products in the borehole, wherein acoustic waves are propagated into the tubing string (tubing) using an ultrasonic emitter, and the downhole products are degassed. When production of downhole products is terminated in the flowing mode, the downhole products are additionally lifted using a pump installed in the tubing below the ultrasonic emitter and a valve placed in the tubing above the pump, but below the ultrasonic emitter, and containing a central channel connecting the in-tube space zones of the tubing below and above the valve installation site and a side channel connecting the annular space of the tubing with the in-tube space of the tubing above the valve installation site. When the pump is operation, the central channel of the valve herein opens, and when the pump is put out of operation, the central channel of the valve closes, and the side channel of the valve opens. Also proposed is an apparatus for the implementation of the method.

EFFECT: higher production efficiency of downhole products and expanded scope of application of the method and the apparatus.
