Products>>Project Development>>Test and Analysis of dynamic impact Energy Propagation and attenuation of Reservoir Rock

High displacement hydraulic fracturing, hydraulic oscillatory fracturing, pulse wave fracturing, cavitation fracturing and other fracturing techniques will form dynamic impact energy during construction process. The propagation and attenuation of this energy in carbonate rocks with different structures (cracks, fractures and holes) directly affect the fracture distance and fracture volume of artificial cracks. By defining the propagation and attenuation characteristics of energy in rock mass, the theoretical relationship between energy and time and distance is established. It provides powerful guidance for the theoretical study of dynamic rock fracture morphology and the quantitative design of pulse wave fracturing.

Theoretical analysis of dynamic impact energy propagation and attenuation of fracture and fracture-hole carbonate rocks

Based on the experimental data of fracture and fracture-hole carbonate rock in dynamic experiment, the law of impact energy attenuation is analyzed, and the characterization method of predicting explosion impact energy attenuation characteristics of carbonate rock is established based on theoretical analysis.

环亚国际娱乐app下载The developed software is based on the experimental data of fracture and fracture-hole carbonate dynamic impact and combined with theoretical research, which can predict the impact energy attenuation characteristics of carbonate explosion. Because the research and development of the software requires profound basic theory of explosion mechanics and explosion experiment technology ability, so it is hard to exploit. The software is the first dynamic impact energy calculation software directly aimed at fracture-hole carbonate rock, and there is no competition with the same kind of products at present.
