摘　　要：岩芯钻探经常遇到构造复杂、裂隙发育、地层破碎等地层,造成钻进困难,效率低下等问题。微泡的特殊结构使微泡钻井液在漏失地层具有堵漏材料的特性;同时,由于其优良的流变特性和润滑性能,携带岩粉能力强,有利于提高岩芯采取率、机械钻速和钻探质量,降低了钻探成本。本文介绍了微泡钻井液特性,并结合现场实践讨论了可循环微泡钻探技术在岩芯钻探中的多重功效。For core drilling it is difficult to drill and of low efficiency when the formations are complicated structured with fractures and fragments. Micro-bubble drilling is of special microstructure and could be used as material to control lost circulation, in the meantime micro-bubble drilling fluid has high cutting-carrying capability, is propitious to increasing core sampling and penetration rate, and drilling quality with lower cost. This paper introduced properties of micro-bubble drilling fluid and discussed its multi-functions for core drilling.
