An Experimental Study on the Prediction of Formation Drillability and Rate of Penetration by Sonic Log Data

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.
