摘　　要：为提高大港油田埕海二区钻井速度,降低钻井周期,利用聚类分析方法对测井资料计算出来的岩石可钻性级值进行处理和分析,建立了埕海二区横向地层岩石可钻性剖面及整个区块内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,可用于指导生产实践。To improve the drilling penetration rate and reduce drilling cycle in Chenghai Region2 of Dagang Oilfield, approach of cluster analysis was used to process and analyze rock drillability calculated from logging data, the rock drillability profile of lateral formation in Chenghai Region 2 and low of vertical rock drillability changes in the whole region were established.The laws of vertical and lateral drillability change are found out, it can be used for guiding the production.

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
