摘　　要：大港油田深部地层可钻性差、岩性复杂、砾石夹层造成钻速低,建井周期长,严重制约着经济的发展。通过作者调研发现,大港油田钻速低的重要原因是钻头使用不合理。为了提高深井的钻井速度,本文从深部地层可钻性出发,对地层进行聚类分析,在每层上结合主成分分析方法,优选出适合该地层的钻头。以达到提高钻速的目的。Deep formation in dagang oilfield poor drillability, lithological, gravel intercalation complex lead to the low drilling rate, cycle of build well is long, seriously restricts the development of the economy. By the author, the survey found in dagang oilfield drilling rate low is the important cause of bit use is not reasonable. In order to improve the drilling speed of deep well, this article embarks from the deep formation drillability, clustering analysis was carried out on the formation, on each layer using the method of principal component analysis, optimized for the formation of the bit. In order to achieve the purpose of improving the drilling rate.
