  To improve the drilling rate, the structure of stepped bit is optimized considering the structural dimension parameters as design variables and the maximum axial displacement as the object function,and then it is tested in field.

  为提高冲击挤密钻进速度,以阶梯钻头的结构尺寸为设计变量,以钻头最大轴向位移为目标函数,对阶梯钻头结构进行优化,并进行了试验研究。
