Hydromechanical vibrator-pulsator for restoring the injectivity of injection wells

Abstract

The article presents a bench model of a vibrator pulsator with a hydromechanical principle of operation designed for processing the bottom-hole zone of the reservoir of injection and production wells, columns of tubing, field pipelines.The design uses a spring-loaded rotary valve. The design of the test bench is described. According to the results of bench tests, the parameters of the pulsator’s stable operation were revealed: at a liquid flow rate of 0.012 m3/s, the oscillation amplitude of the pulsator body was 300 microns, the amplitude of liquid pressure fluctuations was 1.8 MPa at a frequency of 8 Hz. The results of field tests for cleaning columns of pumping and compressor pipes, field pipelines of oil collection are presented.
