METHOD FOR RENEWAL OF WATER WELL PRODUCTION RATE WITH ULTRASOUND

摘要

A method for renewal of water well production rate with ultrasound includes generation of vibrations of directed acoustic field in ultrasonic range, effect of those on perforated intervals of well through immersion to the well of a well acoustic emitter through tubing strings to depth of mudded zones of filters in the period of decrease of water production rate under conditions of operation or termination of operation of wells, carrying out operations of cleaning in pulse mode with defocused cavitation ultrasonic field through transfer with geo-physical cable of signal, and formation of alternating signal of back coupling with its transfer by the same cable to surface equipment for optimization of formed signal. Frequency of de-focused ultrasonic cavitation field is modulated in range selected according to physical-mechanical characteristics of colmatant. Colmatants are dispersed on surfaces of filters.
