GEOLOGIC FRACTURING METHOD AND RESULTING FRACTURED GEOLOGIC STRUCTURE

摘要

Detonation control modules and detonation control circuits are provided herein. A trigger input signal can cause a detonation control module to trigger a detonator. A detonation control module can include a timing circuit, a light-producing diode such as a laser diode, an optically triggered diode, and a high-voltage capacitor. The trigger input signal can activate the timing circuit. The timing circuit can control activation of the light-producing diode. Activation of the light-producing diode illuminates and activates the optically triggered diode. The optically triggered diode can be coupled between the high-voltage capacitor and the detonator. Activation of the optically triggered diode causes a power pulse to be released from the high-voltage capacitor that triggers the detonator.

1. A method of fracturing an underground geologic formation along a section of a bore hole in the underground geologic formation, the method comprising:
positioning a plurality of spaced apart explosive charges along the section of the bore hole; detonating the plurality of spaced apart explosive charges with the explosive charges releasing a total energy equal to or greater than twelve kJ/cc and with greater than 30% of the energy released by the explosive being released in the following flow Taylor Wave of the detonated explosive charges.
