| Abstract: | Based on the structure and inflow mode of the dynamic pressure filtering device, the mathematical method for analyzing the flow field of the drilling fluid in this kind of the filtering device is put forward. The boundary condition of the flow field of filtering device and mathematical model of the cyclone field of the drilling fluid in the device are both established. The radial and tangential and axial motion laws of the drilling fluid are investigated, and the problems of short circuit flow and circulation flow in the dynamic pressure filtering device are analyzed as well. |
