Abstract: The Lagrangian method is used to describe the trajectories of multidispersed suspended particles moving near a spherical collector and to study the microscopic hydrodynamic depositional properties of the particles.The judgement conditions for five different depositional patterns are given.Through the correction for the flow field, the relationship between the microscopic change of the particle concentration and the local depositional properties is obtained.

Key words: Suspended particle, Particle plugging, Formation damage, Dynamics, Hydrodynamics in porous media
