摘要：
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.
