Both traditional theoretical analysis method and experimental test method can not obtain the characteristics of flow field mainly due to the following two points: first, the visualization methods such as staining PIV and tracer method can not be used to measure the flow field which has high concentration and poor visibility; second, at present, all of the contact velocimeter can not test the velocity vector of cementing slurry flow field accurately.	cache/ijassa-325.pdf	txt/ijassa-325.txt
