Subbotin name popup.description1 Development of the methods for intensification of rational ecologically safe extraction of minerals based on the combined use of wave disturbance, surface-active substances, the action of electric discharge, and gas detonation on the borehole zone popup.description2 The research purpose is to develop methods for intensification of rational environmentally safe mineral extraction based on the combined using of wave disturbance, surfactants, the action of electric discharge and gas detonation on the near wellbore zone. It was established that during combined action of electric discharge in a mixture of WOE with the addition of 0.3% NMK-21, the pressure on the wall of the wellbore column was higher in 1,5 times than in water and in NMK-21 solution. It was found that with fixed initial parameters of the properties of the fluid, rock formation, size of the well and contamination of the near wellbore zone, at de ≥ 2, presented flow rates of well did not change. The significant influence of the parameter de on the presented flow rates in the interval 0 < de ≤ 2 was shown. It was found that during cyclic loading for four hours of a rectangular sandstone sample, the decrease of the speed of ultrasound propagation in it when it was sounding through the thickness of the sample was 12% and that was greater in 3.9 times than the decrease of the speed of ultrasound propagation in it when it was sounding through the width of the sample. The relaxation time of the speed of ultrasound propagation was greater in 2.25 times compared to the time of cyclic loading. The design of a gas-impulse device for the study of negative pressures under its action in a wellbore model has been developed. Scope – oil, gas, condensate and natural water production.
