摘要：
On the rotary drilling system, the technologies for fracturing and cutting hard rock are mainly mechanical rock breaking methods by use of improving bottomhole water horse power and bit energy, and the working life and rock breaking efficiency have much room for improvement. Microwave crag broken is a thermal assisted rock breaking method which could melt rocks. Microwave assisted rock breaking method will not bring new impact, wear and tear, instead, the microwave pretreatment on the rock reduces the difficulty of breaking rock and prolongs the service life of the drill bit. Under the combined action of microwave heat and mechanical energy of PDC bit, the rock breaking efficiency is improved greatly, and the drilling cost is reduced significantly.
