摘　　要：扼要叙述了室内试验的方法，介绍了用声波测井数据预测地层可钻性及钻速的试验研究概况．在详述对试验数据分析处理过程的基础上，给出了室内声波速度与岩石可钻性级值之关系式以及室内声速与测井地下声速之关系式，并首次提出了应用现场声波测井资料预测钻速的数学模型．By briefly describing the testing methods in the laboratory, the s have introduced the experimental study on the prediction of formation drillability and rate of penetration by sonic log data. On the basis of describing the analyzing and processing procedures for test data in detail, it has given the relationship between sonic velocities in the lab and rock drillability grade values as well as the relationship between sonic veloctities in the lab and those downhole. It shows for the first time the mathematical models for predicting rate of penetration by using field sonic log data.
