| Abstract: | The two-phase fluid flowing mechanism in one-dimensional displacement is studied based on the non-Newtonian fluid mechanics, and the flowing field of displacement flow is also derivated by numerical computation technique. The resulting tendency from the study meets well with the experimental tendency, and the two popular models at moment thus can be defined as false and therefore corrected. The study provides a reliable backup for the reasonable designing of hydraulic parameters in field cementing of slim holes. |
