Abstract:

Through an introduction to the application of the energy law for rock drillability in oil.fields,the paper determines the applied extent of its index Kn for lithology of the formation and proves a much easier and better response of the index Kn to the true drillability changes in the well, The prediction of the drilling velocity thus obtained can almost be identical with the true one.

Key words: Rock drillability, Cuttings analysis, Grain size, Prediction, Drilling velocity
