Abstract

Deformable gel particles (DPGs) has been used for performance control in petroleum industry. The filtration behaviors of DPGs including shearing, plugging, deformation, and breakage, which is much different from Deep bed filtration. Although some empirical knowledge or models have been reported in literature, there have been few quantitative investigations or mechanistic interpretations to such behaviors. Therefore, quantification of DPG filtration in porous media is extremely essential. In this paper, we first conducted experiments to directly observe and measure the characteristics of a DPG transport in a variable-diameter capillary. After that, experiments of DPG transport in pores were conducted to study and quantify the plugging, shearing, and breakage behaviors in different scenarios using sand packs. Finally, the above quantitative knowledge were used to optimize DPGs treatment for EOR, and oil displacement experiments of parallel sand packs with interlayer were carried out to apply and validate the novel method.
