Abstract

The breakage and deep plugging law of deformable gel particle (DGP) in porous media are not clear. In this study, the flow experiments of DGP were carried out, the changes of residual resistance coefficient (RRC), DGP size and concentration along the way were measured, and the breakage and plugging law of DGP was quantitatively characterized. The results show that the passage after breakage is the main migration behaviors of DGP, and DGP are reduced by half in front of the porous media. Breakage is an important reason for the continuous decrease of concentration, particle size and RRC. However, the DGP can plug in deep of the porous media after breaking. The higher the injection rate or the larger the DGP size, the faster the breakage along the injection direction, and the worse the deep plugging ability. The empirical model can be used to optimize the DGP parameters in oil field.
