反循环钻探管路中空气的运动参数包括流量、流速、压力、差压，相互间存在一定的函数关系，这些参数对携带固相有很大影响。测试运动参数并找出规律性，探讨介质携带固相的运动机理，对反循环钻探施工有一定的指导意义。介绍了测试内容及目的，并对测试结果进行了分析。
Reverse circulation drilling air movement parameters include flow, velocity, pressure, differential pressure, there is a certain relationship between each other, these parameters have a great influence on the carrying solid phase. Test the motion parameters and find the regularity, and discuss the movement mechanism of medium carrying solid phase, which is of guiding significance to reverse circulation drilling. The content and purpose of the test are introduced, and the test results are analyzed.
