摘　　要：玉门青西油田岩石可钻性差,给钻井工程带来很大难度。为提高钻井速度,降低钻井周期,利用测井资料进行了岩石可钻性解释、处理和分析,建立了该油田横向地层岩石可钻性剖面及该区块内每一口井地层岩石可钻性纵向变化规律,找出了该区块地层岩石横向及纵向可钻性变化规律,为钻头优选提供有利的理论依据,从而应用于生产实践过程。It is most difficult to increase drilling penetration rate and reduce drilling cycle during drilling because of poor rock drillability in Qingxi area Yumen Oilfield.Rock drillability is explained and analyzed through the explanation of logging date.The lateral stratigraphic rock drillability sections in Qingxi area Yumen Oilfield are established and the changing law of vertical rock drillability is founded for every well in the oilfield.The changing laws of lateral and vertical stratigraphic l rock drillability are founded in the oilfield,which provides the beneficial theories for the bit optimization.

关 键 词：岩石可钻性 可钻性剖面 钻头优选 变化规律 地层剖面
