摘要: 自Teale R.首次提出机械比能原始模型以来,已有研究人员研究了诸多改进模型并得到了应用,但大部分模型未明确钻压和扭矩等关键参数的物理意义。以实例进行比较和验证表明,在引入钻头有效钻压和有效扭矩,并提出有效钻压和有效扭矩的计算方法后,模型分析精度得到明显提高。

关键词: 有效钻压和扭矩, 改进机械比能, 有效岩石抗压强度, 钻头选型, 参数优化

Abstract: Since R. Teale first proposed the original mechanical specific energy model,many improved models have been studied and applied. However,most models do not clarify the physical significance of key parameters such as weight on bit (WOB) and torque. This paper introduces the effective WOB and effective torque,and proposes a calculation method for effective WOB and effective torque,which significantly improves the analysis accuracy. An example is used to compare and verify the results.

Key words: effective WOB and torque, improvement of mechanical specific energy, effective rock compressive strength, bit selection, parameter optimization
