摘要
通过室内试验，确定了岩石可钻性与岩石力学性质（ 硬度、抗压强度和塑性因数等） 的关系， 并把声波测井资料与牙轮钻头可钻性相结合，给出了用测井数据表示岩石可钻性级值的统计模型． 分析表明： 岩石的强度和硬度是影响岩石可钻性的主要因素，塑性因数对岩石可钻性影响较小． 岩石的纵、横波时差分别反映岩石不同物理性质，在建立可钻性计算模型时，需用多元回归方法．
Based on indoor experiment results, this paper determines the relationship between rock drillability and mechanic properties (such as hardnees, compression strength and plasticity). A statistical model about the relationship between acoustic logging data and rock drillability is established. Statistical analysis indicates that hardnees and strength are the main factors which affect rock drillability, and the effect of plasticity is relatively small. Time difference between longitudinal and lateral acoustic waves reflects different physical properties of rock. Multielement regression method is used to establish the statistical model about rock drillability.
