摘　　要：选用合理钻头是提高机械钻速 ,降低钻井成本的重要途径之一。利用测井资料预测可钻性计算模型编制的计算机软件 ,建立了盐城地区连续的可钻性剖面 ,并根据分层计算的可钻性级值 ,结合每米成本法 ,优选出适合盐城地区的钻头选型 。Reasonable selection of bit is one of the important approaches to increase ROP and decrease drilling cost.The logging information is used to predict drillability of rock,and the computer program is written,therefore,the profile of continous rock drillability has been established in Yancheng area.According to the value of rock drillability and method of cost for every meter,the optimum bits are selected,and scientific evidences have been provided for the reasonable use of bits.
