岩石可钻性能量法现场实验研究

本文介绍了岩石可钻性能量法在油田现场实验研究的成果：确定其可钻性指标Ｋｎ对地层的适用范围；证明Ｋｎ指标比其他可钻性指标能更容易、更好地反映出井下实际地层可钻性变化情况；用Ｋｎ指标预测钻速与实际钻速接近．

Application of Energy Law for Rock Drillability in Oil Fields

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.
