摘要

潜孔锤空气动力钻进具有破岩效率高、钻进速度快、设备可快速部署、综合成本较低的优点,将定向钻进技术与空气动力潜孔锤相结合,则可以完成空气动力钻进的定向井,使水资源钻井、煤层气钻井、过采空区钻井、抢险救灾等工程在快速施工的前提下,还能精确地控住轨迹、命中预定的靶区,使钻井的质量和效用上升到一个新的层次。
        DTH hammer aerodynamic drilling has many advantages such as high rock breaking efficiency,fast drilling speed,rapid deployment of equipment and low comprehensive cost.Combining directional drilling technology with aerodynamic down-the-hole hammer can be completed.The directional wells drilled by aerodynamics enable water drilling,CBM drilling,over-drilling,disaster relief and other projects to accurately control the trajectory,hit the intended target area,and make the drilling well under the premise of rapid construction.The quality and utility have risen to a new level.
