| 中文摘要:MK-2井钻探工程是国家地质大调查计划“钾盐资源调查评价”项目中的施工工程，由于该工程所在区域地层高研磨性、高弹塑性的特点，致使钻井施工缓慢。针对这一难题，研究设计了新型巴拉斯钻头，并通过现场试验验证了这种新型钻头在该类地层的适应性，同时总结出了相应的钻进工艺，为以后钻进该类致密泥岩地层提供了有效的破岩工具。 |

| Abstract:MK-2 well drilling is a part of “potash resources investigation and assessment” project in the national geological survey program. Because of the high abrasive and high-elastic-plastic characteristics in this area， the drilling rate was very slow. In view of this situation， this new Balas bit was proposed and designed and the field tests were made to verify the adaptability of this new type of drill bit in such formations; the corresponding drilling technologies were summed up at the same time， which could be an effective rock breaking tool for drilling in the dense mudstone in future. |
