Fine migration inevitably occurs during the process of fracturing production in argillaceous unconsolidated reservoirs. Using the API conductivity cell simulate the process of the production of the reservoir. The damage to conductivity caused by fines migration in the pack and the factors affecting such migration are analyzed. The result indicates that clay are likely to aggregate and be retained in the prop pant pack because of the adsorption and deposition, thereby resulting in pore throat plugging, which causes serious damage to fracture conductivity. The mobility and retention of clay in the prop pant pack are affected by flow rate, fracture closure stress and fines property. This research is important for the further research.
