The wellbore trajectory control is the key and difficult point in slim hole cluster drilling technology.

井眼轨迹控制是小井眼丛式钻井技术的重点和难点，文中探讨了钻具组合、上部井眼曲率、钻井参数以及钻头选型对小井眼轨迹控制的影响，并建立了相应的井眼轨迹控制模式。

When the speed of piton changes from several positive meters per second to negative during short time , a huge transient impacting force acts on the piston. The force spreads in the piston with stress wave. Converging force will become at some sections, which can destroy the piston.

从风动冲击器的工作原理可以得知，风动冲击器的活塞在高压气流的推动下，反复冲击钻头，冲击时活塞的速度由向下的几米每秒在极短时间内反弹为向上的速度，因而对活塞产生一个极大的瞬时冲击力，该力以应力波的形式在活塞内传播，就会在活塞的某些断面产生应力集中，造成活塞的破坏。
