Pressure on the Surface of a Well Casing Created by an Electrical Discharge in Water

Based on the combined use of the method of mathematical modeling of the process of electric discharge impact on the bottom-hole zone of a water intake well and a physical experiment, the pressure distribution on the surface of the casing pipe was determined. Based on physical experiment data, the mathematical model was verified and refined under conditions of low capacitance of the capacitor bank and low inductance of the discharge circuit. The readings of the pressure sensor on the surface of the casing pipe were coordinated with the results of mathematical modeling, taking into account the interrelated physical processes in the discharge circuit, the discharge channel and the liquid filling the casing pipe of the water well.
