“…However, the dissolution rate of montmorillonite slows down when the concentration of OHions in bentonite decreases. The swelling strain of bentonite also decreases with increasing Na2CO3 concentration and reaction time (Panahov et al, 2023;2019;2018). The void coefficient at saturation of samples dissolved in the same solution for the same reaction time can be expressed by the fractal swelling model After primary adsorption, bentonite macromolecules provide strong bonding of dispersed aggregates to the rock surface, forming a stable mass in the dynamic flow.…”

The paper describes the formation of plugging aggregates deep within the formation, on the walls of the pore channels and in the free pore space, resulting in a local increase in flow resistance due to the complete blockage of individual pore channels. A model of growth of colmatant detached from the walls of the porous medium in the near wall flow is proposed, which takes into account not only the influence of hydrodynamic flows on chemical reactions occurring in the system The model takes into account not only influence of hydrodynamic flows on chemical reactions in the system, but also inverse influence of growing clay ball on flow pattern. Industrial testing of proposed bridging compound was carried out on Binagadi oil field (Azerbaijan).
