摘　　要：利用钻进参数仪采集的各种岩石的钻速、钻压、转速三个参数的大量数据进行回归分析，计算各种岩石的视可钻性指数，把钻进中所计算指数与各岩石指数范围进行比较，即可实现实时判层。Through regression analysis on large data of three parameters (drilling speed、drilling pressure and turning speed) in various rocks collected by instrument of drilling parameters, and calculated indexes of apparent drilling feasibility on different rocks, and compared indexes during drilling with the indexes scope of rocks, may be realized lithological judgement in actual time.

关 键 词：实时判层 钻探参数 破碎比 钻进参数仪 钻速 钻压 转速
