High Voltage Electric Pulse Drilling: A Study of Variables through Simulation and Experimental Tests

With the deepening of drilling depth, difficulty engineering increases gradually due to complex geological conditions. The traditional mechanical method shows problems high energy consumption, low efficiency, long cycle and cost. Because characteristics rock, abrasiveness rock causes great wear bit, which becomes an important factor affecting rate. High voltage electric pulse (Abbreviated as HVEP later in this paper) technology is a new developed past several decades. uses plasma channel, water jet or shock wave generated by discharge break rock. It has environmental protection, directional breaking, easy control breaking process fast speed face hard In paper, mechanism deep are studied, functional test carried out.
