In order to study the influence of suspended particles and emulsified oil droplets on the water absorbing capacity in produced water reinjection process, we analyzed the suspended particles filtration model by the depth filtration and formation of the external filter cake, and optimized the solution of the model parameters(the filtration coefficient λ and the formation damage coefficient β). Based on the solution curves fitted by the core flooding experiment data, and by the numerical solution of the transcendental equation, we obtained the variation rule of filtration coefficient(λ), formation damage coefficient(β) and impedance slope(m) under the influence of different phase suspended particles. Then we got the impedance of the depth filtration and filter cake formation with piecewise fitting and calculated the particle concentration distribution of the core.

Key words: depth filtration, filter cake formation, filtration coefficient, formation damage coefficient
