【 摘 要 】

In the oil-field development, blocking caused by impurities leads to a decline in oil production. The high-voltage pulsed deplugging technology can be applied successfully in oil deplugging. One of the key problems in this technology is the influence of the electrode model on discharge characteristics. In this paper, the electrode structure was studied. Firstly, the influence of the electrode gap on electric-field intensity was studied by using ANSYS simulation. Secondly, a high-voltage pulsed discharge experiment system was built and the discharge characteristics were studied under different static pressure when the electrode gap varied. The results show that the larger the electrode gap, the lower the electric strength and the longer the time delay. Short breakdown time delay would make greater energy of impact waves and better blockage relieving effect.
