对钻孔进行冲洗的流体参数分析

Analysis of parameters of fluids in a boring hole

运用工程流体力学和两相流体力学知识对钻孔时进行冲洗的流体参数进行分析 ,用以指导工程实践。建议注意环形空间和环形缝隙的区别 。

This paper analyzes the parameters of drilling fluids in a boring hole with engineering hydrodynamics and two phase engineering hydrodynamics so as to guide engineering practice.In order to avoid mistakes due to misunderstanding the structure of the hole,we should pay attention to the difference between anular space pipe and narrow anular space pipe.
