摘要
随着钻孔深度的增加,从设备到钻探工艺都产生了一系列新问题,拟就深孔钻探经常遇到的关键问题,如钻孔结构、钻探设备选择、钻柱、钻具组合、钻头和扩孔器、冲洗液等,提出一些应当引起注意的技术措施。
A series of new problems,from equipment to drilling techniques,has been arising as the borehole becomes deeper and deeper.The article provides some technical measures to manage some crucial problems encountered in deep hole drilling,which covers borehole structure,drilling equipment selection,drilling string,borehole assembly,bit,reamer,and drilling fluid.
