8 μm). After 8 days of hydration expansion, although the expansion multiple is small, it can coalesce and enhance the plugging effect, which can adapt to a wider range of permeability, ranging from 200 × 10-3 to 3000 × 10-3 μm2 (200 × 10-3-1500 × 10-3 μm2 for traditional microspheres). Under the same conditions (heterogeneous core), compared with the traditional microspheres, the core-shell microspheres have the characteristics of coalescence. Therefore, its fluid diversion effect is better, and the oil recovery is increased by 5.5%.
