摘　　要：随着深井、超深井逐步成为油气开采的一种趋势,提高破岩效率、钻进速度至关重要。为了提高PDC钻头在层理岩层的破岩效率,分别设计伺服液压夹持系统,液压钻进系统,液压高速旋转系统,高频径向冲击系统和高频轴向冲击系统,对钻杆在不同钻压、不同转速、不同冲击频率、不同冲击力下,对破岩效率、钻进速度进行了规律研究。As deep and ultra-deep wells gradually become a trend of oil and gas exploitation, it is very important to improve rock breaking efficiency and drilling speed. In order to improve the PDC bit in bedding rock fragmentation efficiency of rock strata, the design of servo hydraulic clamping system respectively, hydraulic drilling system, hydraulic high-speed rotation system, high frequency and high frequency axial radial impact system impact system for drill pipe in different drilling pressure, rotating speed, under different impact frequency, impact on the rock fragmentation efficiency, the drilling speed in the study of law.
