Aiming at the dual technical challenges of WSO and sand control in high water-cut and sand-producing reservoirs, a kind of selective WSO/sand stabilization integrated particle was developed by using oil-soluble resin particles, sodium-based bentonite, lignosulfonate dispersant, and cationic polyacrylamide as main raw materials.Performance tests including sand stabilization and selective WSO show that:The median particle size of this particles is 8.51 μm and the water-phase dissolution rate is 9.83% with a core plugging rate of 84.5%, while the oil-phase dissolution rate is 82.61% with a core plugging rate of 15.8%. It can bond sand grains in the core into clusters, increasing the median sand grain size by more than 8.8 times and the critical sand-producing velocity by more than 20 times.indicating an obvious selective plugging and sand stabilization effect.
