Abstract: Based on attribute measurement,attribute hierarchical model is established by analyzing judgment criterion and attribute judgment matrix.The model,which combined attribute recognition theory with hierarchical analytical method,is a new unstructured decision-method.The procedures and hierarchical structure of the model is studied in drill bit optimization.Based on bit database,the model is applied in deep drilling practice in Daqing Oilfield,and bit optimization design in District Shangzhi is taken as an example to analyze the model,finally the scenario of bit is presented.

Key words: attribute, hierarchical analysis, recognition, judgment matrix, bit, optimization, drilling

摘要： 在属性测度的基础上,通过分析判断准则和属性判断矩阵,建立了属性层次模型。该模型将属性识别理论和层次分析方法结合在一起,是一种新的无结构决策方法。将该方法应用于钻头优选技术中,研究了属性层次模型进行钻头优选的步骤和层次结构。结合大庆油田深井的钻井实际,基于该油田深井钻井使用数据库,利用所建立的模型对大庆油田的深井钻头进行了优选,以尚志地区为例进行了实际分析,给出了该地区钻头优选方案。
