Abstract

The invention relates to the field of pulse power technology applications and energy exploitation technology, in particular to a method of electrically exploding wires to generate shock waves in waterby driving energy containing mixtures. The method of the electrically exploding wires to generate the shock waves in water by driving the energy containing mixtures comprises the following steps thata specific pulse power drive source is used to drive the wires of different materials, different diameters, and different lengths to cause an electrical explosion, the phase transition time, discharge current waveform and emission spectrum intensity of the corresponding wires are recorded; shock wave loads of different formulations are made and underwater shock wave experiments are correspondingly performed; shock wave probes are used to measure shock wave waveform and compared with the required waveform to determine the corresponding relationship between shock wave specific impulse and the shock wave loads; and according to the required shock wave parameters and the corresponding relationship between the shock wave specific impulse and the shock wave loads, a corresponding shock wave load is selected to be placed between the high and low voltage electrodes at the output end of the pulse power drive source and is driven under water to generate a controlled shock wave.

Description

technical field [0001] The invention relates to the technical field of pulse power technology application and energy mining, in particular to a method for generating shock waves in water by driving an energetic mixture with a metal wire electric explosion. Background technique [0002] At present, the world's primary energy mainly relies on fossil energy, and non-fossil energy accounts for only about 15% of primary energy consumption. The development of fossil energy requires certain modification of reservoir rocks in order to obtain industrial output. At present, the only technical measure for improving the permeability of the reservoir (coal seam) is the mechanical method, that is, applying pressure to the reservoir in the well in a static or dynamic manner, causing the reservoir to rupture to accumulate more oil and gas. [0003] The static method represented by hydraulic fracturing uses high-pressure water flow to exert huge pressure on the reservoir, causing the reserv...
