The electrical explosion of wire（EEW） is gradually acted as a physical and environmentally friendly enhanced oil recovery（EOR） technology in petroleum industry. In order to establish the relationship between the shock waves（SWs） and EEW

the process of underwater EEW was investigated under the different energy deposition based on the measurements of the current

voltage and shock waves. Through the analyses of current

voltage

resistance

and energy deposition

the effect of capacitance and stored energy of capacitor on discharge time

energy deposition in each stage and SWs were studied. The results show that the capacitance of capacity and stored energy has a negligible effect on the energy deposition in solid and melt stage of wire

except in vaporization process. The energy deposition rate in vaporization process under the discharge by capacitor with 30 μF capacitance is higher than that with 60 μF capacitance. During the wire discharge process

the peak pressure has a close relationship with the energy deposition in vaporization process

and they have the same change tendency.
