Research on the statistical analysis for repeated discharge breakdown voltage of plasma pulse equipment

Abstract In order to enhance the output of unconventional oil and gas, it is essential to modify their reservoirs. Plasma pulse technology is a new reservoir modification technology, which hboratory setting. The energy released (123.93 J), peak power (40.57 MW) and average power (17.71 MW) of plasma pulse equipment during the main-discharge phase was studied, and the statistical characteristics of repeated discharge frequency (0–25 Hz) were explored in depth. Under the conditions as the characteristics of safety and environmental protection compared with the traditional technology. Discharge testing of plasma pulse equipment was conducted in a laof initial discharge frequencies of 14 Hz and 20 Hz, Allometric1 and ExpAssoc curve-fitting functions of breakdown voltage varying with the number of discharge were established respectively, as well as Rational2D surface-fitting function of breakdown voltage varying with the number of discharge and discharge frequency. And these statistical analysis reveal that with the increase of discharge number and discharge frequency, the breakdown voltage shows a nonlinear decline rule. The results indicate that the research presented in this paper is important to reveal the statistical laws of repeated discharge breakdown voltage of plasma pulse equipment, as well as for prediction performance of breakdown voltage.
