Enskog theory is extended for the description of the self-diffusioncoefficient of patchy colloidal fluid in disordered porous media. The theoryincludes the contact values of fluid-fluid and fluid-matrix pair distributionfunctions that are modified to include the dependence from the so-called probeparticle porosity, $\phi$, in order to correctly describe the effects oftrapping the fluid particles by a matrix. The proposed expressions for themodified contact values of fluid-fluid and fluid-matrix pair distributionfunctions include three terms. Namely, a hard sphere contribution obtained byus in the previous work [Holovko M. F., Korvatska M. Ya., Condens. MatterPhys., 2020, 23, 23605], the depletion contribution connected with thecluster-cluster and cluster-matrix repulsion and the intramolecular correlationinside the cluster. It is shown that the last term leads to a remarkabledecrease of the self-diffusion coefficient at a low fluid density. With adecreasing matrix porosity, this effect becomes weaker. For intermediate fluiddensities, the depletion contribution leads to an increase of theself-diffusion coefficient in comparison with the hard sphere fluid. For asufficiently dense fluid, the self-diffusion coefficient strongly decreases dueto a hard sphere effect. The influence of the cluster size and the type ofclusters as well as of the parameters of porous media is investigated anddiscussed in detail.
