A coal reservoir excitation by the repeated strong pulse waves of high energy accumulation was an originality new technology developed by Chinese sci
entists based on the principle of the nuclear explosion shock wave. The discovery of the preliminary work showed the permeability improved feasibility and availability 0
f the coal reservoir. But the basis study lagged behind the engineering discovery and the further research and development and the promoted application of the technol
ogy were urgently needed to make a breakthrough at the bottleneck of the basis study. Faced to the major technical requirement of the high efficient economic develop
ment of the coalbed methane in China, the paper analyzed the study status on the shock wave fracturing and permeability improved field of the coal reservoir, stated th
e basic principle of the coal reservoir fracturing and permeability improved with the repeated strong pulse wave of the high energy accumulation, summarized the prelim
inary site experiment of the technology and the engineering discovery effect, and refined the scientific problems to be solved along the direction. The paper discussed t
he breaking dynamics features of the coal reservoir and the coupling role mechanism of the geological and engineering factors under the guidance of the repeated stron
g pulse waves of the high energy accumulation, in detail explained the key scientific problem of the wave-flow-coal interreaction under the guidance of the repeated pul
se waves, which would be the most important basis to further research and development and to improve and apply the permeability improved technology of the coal res
ervoir.
