钻井模型中两个重要因素的处理技术

DEALING METHOD OF TOW FACTORS IN DRILLING MODEL

摘要: 钻井实践表明,地层因素和钻头类型是影响钻井过程的两个十分重要的因素。以往建立的钻井模型一般都将这两个因素的作用融合在其它因素中或用一个系数来代替,而不论是什么地层和钻头类型又都使用同一钻井模型或系数,这显然是不恰当的。采用近十几年发展起来的"非数量因素数量化"的方法对这两个因素进行了处理,其结果证明,可以用这种方法有效地提取地层信息和钻头类型信息。

Abstract: Drilling practice show that formation and bit types are tow important factors effected drilling.In past drilling model,it is difficult to consider effecting of formation and bit separately.This paper introduces a new method to deal with the drilling factors.Result shows that this method can obtain information of formation and bit.
