摘　　要：获取钻进参数进行能耗分析是实现高效钻进的手段。为探究旋转钻进破岩过程中钻进参数与破岩能耗的相关性,通过室内钻进试验研究钻进参数对钻进速度的影响;提出了能时密度指标,并通过数值模拟对旋转破岩过程中的能耗特征进行分析。研究结果表明:旋转钻进岩石的轴压和转速与钻进速度成正相关,破岩能耗与钻进位移呈线性关系,钻进千枚岩的最佳试验参数为轴压650 N、转速400 r/min;基于钻进比功建立钻进破岩能时密度公式,能时密度随轴压和转速的增加呈先下降后上升的趋势,能时密度集中于0.0069 J/(mm^(3)·s)时能耗最低,钻进效率最优。Obtaining drilling parameters for energy consumption analysis is an important means in achieving efficient drilling.In order to explore the correlation between drilling parameters and energy consumption in the process of rock breaking by rotary drilling,the influence of drilling parameters on drilling speed was explored through indoor drilling tests.The energy-time density index was proposed,and the energy consumption characteristics in the process of rotary rock breaking were analyzed by numerical simulation.The results show that the axial pressure and rotational speed of rotary drilling rock are positively correlated with drlling speed,and the energy consumption of rock breaking is linearly correlated with drilling displacement.The optimum test parameters for drlling phyllite are axial pressure of 650 N and rotational speed of 400 r/min.Based on the specific work of drilling,the formula of energy-time density of rock breaking was established.The energy-time density decreases first and then increases with the increase of axial pressure and rotational speed.When the energy-time density is concentrated at O.0069 J/(mm^(3).s),the energy consumption is the lowest and the drilling efficiency is the best.
