Simulation Based on CFD of Drilling Fluid Screening Process

Screening process through the establishment of a mathematical model to calculate the amount of processing shaker is difficult, complex process, low accuracy. In this paper, based on the CFD simulation of the drilling shaker screening process which realized the drilling fluid flow through sieve and the free surface of liquid flow visualization simulation. The screen mesh and mud cake with a series of porous media simulation, the dynamic meshing technique was adopted to achieve the the vibrating screens movement of drilling fluid on the surface of the screen. Analysis of multiple parameters (such as screen mesh, vibration frequency) on the influence of drilling fluid flows through screen. Research results show that the proposed method of CFD to calculate the rate of the drilling shaker is feasible. Have a important reference value to solve the problem of capacity calculation.
