Abstract

Abstract

Composite electro-thermal chemical explosion (CETCE) was used to generate strong shock waves (SWs). This paper introduces the mechanism and effects of SWs generated by CETCE on reservoir stimulation and gives the discharge parameters and discharge load structure used to ignite energetic materials (EMs). The SW fracturing effects experiments were carried out. The dynamic strain and desorption related parameters, including porosity, permeability, strengths of extension and compression were measured and compared with those before the shock experiments. The results show that, the SWs generated by CETCE can generate the dynamic strain of 1000-1500, and visual cracks appear on and in the samples. The average porosity of sample increases from 15.24% to 15.62%, average permeability increases from 1.749 0910-3m2 to 2.467 0810-3 m2, and strengths of extension, compression and shear decrease by about 30% overall.
