Abstract

The invention discloses a horizontal in-hole type high-power shock wave generating device and method. Battery direct current is inverted into power frequency electricity through an inverter, the powerfrequency electricity is boosted into high-voltage electricity through a transformer, the high-voltage electricity is rectified into high-voltage direct current to charge an energy storage capacitor,after the voltage of the energy storage capacitor reaches the rated voltage, a controllable gas switch is broken down and conducted to send pulse high-voltage large current to an energy converter, the pulse high-voltage large current drives an electrode in the energy converter to generate electric explosion or electrochemical explosion, high-power shock waves are excited in water, and the high-power shock waves penetrate through a wellbore screen pipe or a casing pipe to be perforated and act on a reservoir stratum. Therefore, the unblocking, the fracture forming, the communication and the extension of original fractures can be achieved within the effective action radius, so that the purpose of modifying the reservoir stratum is achieved.

Description

technical field [0001] The invention relates to the field of pulse power, in particular to a horizontal hole type high power shock wave generating device and method. Background technique [0002] Intensive drilling, deep hole pre-splitting blasting, carbon dioxide blasting, hydraulic jet cutting and other technologies are the main methods of coal mine gas extraction at present. The intensive drilling method increases the number of drilling holes per unit area to increase the gas drainage volume. The operation process is simple, but the construction period is long, the drilling and pipeline costs are high, and the effect is not ideal in low-permeability reservoirs. The deep hole pre-splitting explosion method places explosive (gunpowder) columns hole by hole or every hole in one or several holes, detonates at the same time, and enhances the penetration of the entire implementation area at one time, which can improve the gas drainage effect, but the safety is poor , The treat...
