摘要
本文从热传导理论入手,将理论推理与试验相结合,确定了热机碎岩钻进过程中温度变化与深度的关系。然后根据经验,给出了用于计算岩层不同深度温度的经验公式,最终通过具体试验数据验证了该公式得可靠性。另外,文中还介绍了热机碎岩钻进中胎体与岩层温度的测温方法。
According to both the theorafieal ratiocination and test results, the relationship of temperature and depth in matrix and rock is given. Based on experience, an experimental formula is finally presented in this paper. The reliability of this formula is checked at the end. In addition, the methods of measuring the temperature of both matrix and rock mass are provided in this paper.
