摘要
对现有钻头选型及指标预测方法存在的问题进行了分析 ,指出了在市场经济条件下 ,现用钻头指标预测方法可能引发的矛盾。提出了利用未确知有理数的最大可信度原则进行钻头指标预测的方法。以某油田的实际钻头使用数据为例 ,作出了这些钻头的钻压、转速、排量、立压、钻速、纯钻时间和钻头进尺等参数用未知有理数表示的可信度分布函数 。
Under the condition of market economy,the contridiction possiblely caused by bit performance prediction method available is studied through analyzing the methods of bit selection and its performance prediction A method for bit performance prediction is proposed based on the most reliable principle of unknown rational number The distributional functions of reliability denoted by unknown rational number are given to the parameters of weight on bit,rate of revolution,displacement,standpipe pressure,rate of penetration,bit working time and footage of bits by using bit operation data as an example taken from an oilfield,which shows that the method is feasible
