摘要
应用相似理论及相似转换法,推导出了模拟实验研究底部钻具组合(BHA)运动状态所遵循的相似指标及相似准则,简单介绍了如何应用该相似准则建立底部钻具组合运动状态模拟实验装置.本文采用BHA运动微分方程为基本方程推导相似准则,推导出的相似准则物理意义明确,可以用来指导BHA运动状态实验研究.
Based on the movement differential equation of bottom-hole assembly (BHA), a set of similitude guidelines and rules following by the simulate experimental research on motion behavior of bottom-hole assembly were derived by the similitude transfom method. Then how to set up the simulate device according to the similitude rules was presented simply.
