摘要
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 formation. 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 the future.
