| Popis: | This study adopted a synthetic oil-swelling material (OSM) as a novel additive in oil well self-healing cement paste (SHCP) to achieve self-healing effect initiated by oil phase when cracks already formed. The OSM with oil absorption rate of 12.78 g/g in kerosene. The mechanical properties of uniaxial tensile fracture elongation up to 208.8% and tensile fracture toughness up to 25.7 kPa, uniaxial compressive fracture toughness up to 1.956 MPa. The results indicated that permeability of SHCP gradually alleviated due to swelling of OSM, and compressive strength obviously increased under the optimal dosage compared to the blank specimen. |
