冲击回转碎岩机理试验研究

Research on the Percussive Rotary Rock Fragmentation Mechanism

摘要:

在模拟孔底冲击回转钻进条件的试验台上,对岩石的冲击回转碎岩机理进行了试验研究,提出了大直径潜孔钻头的合理布齿及钻进参数选择依据.

Abstract:

Laboratory research on the percussive rotary rock fragmentation mechanism have been carried out on the down hole percussive rotary testing bench which simulated the real down-hole situations. The basis for DTH hammer bit insert arrangement and drilling parameter selection presented.
