METHOD FOR OPERATION OF PRODUCT WELL AND EQUIPMENT FOR REALIZATION OF SAID METHOD Russian patent published in 2007 - IPC E21B43/18 E21B43/25 

FIELD: oil extractive industry, namely, technology for increasing operation efficiency of product wells, in particular, wells, operated under complicated extraction conditions.

SUBSTANCE: in accordance to method, electric centrifugal pump and tail with perforated lower part are lowered on tubing pipes. Liquid flows in annular space are isolated. In accordance to invention, hydrodynamic generator of resilient oscillations is mounted in tail, which is activated by flow of liquid being extracted, guided into annular space above its isolated portion by electric centrifugal pump. Isolation of annular space above productive bed is performed with possible control over direction of flows of liquid being extracted. Equipment includes tubing pipes with electric centrifugal pump, tail of tubing pipes with perforated lower part and packer. Tail is provided with source of resilient oscillations, including hydro-dynamic generator of resilient oscillations with resonator. Above the packer, deflector of flow into annular space is mounted. Packer is made with possible adjustment of hydraulic resistance of flow of liquid being extracted for distribution thereof through the source of resilient oscillations and into annular space.

EFFECT: increased efficiency of operation of product well due to creation of most favorable conditions for increasing influx of oil from collector of pool, subject to pollutions and penetrability decrease during operation, or not fully completed during construction of well, and also increased reliability of functioning of well construction elements connected to it hydro-dynamically and meant for extraction of subterranean liquid.
