提出了一种确定三牙轮钻头随钻岩石强度的新方法。该技术采用众所周知的“钻出”测试，使用通常测量的钻井数据，并且不需要钻头参数的知识。对该方法进行了评价，并与Haland(1992)提供的现场抗压强度计算结果进行了比较。结果表明，该方法计算结果合理，易于实现。
A new method is developed for determining rock strength while drilling with a tri-cone roller bit. The technique employs the well-known ''drill-off'' test, using commonly measured drilling data, and does not require knowledge of drill bit parameters. The method was evaluated with drill-off test darn collected from the Gas Research Institute's SFE (staged field experiment) well no. 4 and compared with calculated in-situ compressive rock strengths provided by Hareland (1992). The results indicate that the proposed approach produces reasonable results and is easily implemented.
