运用普通钻头与自形成同心径向环齿金刚石钻头的经济比较分析

Economy analysis between ordinary bits and concentrical segmented diamond bit

文章采用效益指数法对普通钻头与自形成同心径向环齿金刚石钻头进行了比较分析,通过讨论主要得到了影响普通钻头与自形成同心径向环齿金刚石钻头钻探成本的机械钻速、钻头总进尺、钻头费用等主要因素及规律,并强调了钻头选型中重视技术经济性的重要性。

The benefit index method is used to analyze the ordinary bits and concentrical segmented diamond bit in this paper.Through the discussion,it comes the rule that how the drilling speed total,bit footage,bit cost influence the benefit index of ordinary bits and concentrical segmented diamond bit.Also it emphasizes the importance of bit selection through the benefit index method.
