Abstract:

Aiming at the profile control and flooding technology of cross-link polymer microspheres- polymer composite proposed
by our research team,solution properties and microstructural morphology of cross-link polymer microspheres - polymer
composite system in aqueous solution were studied. Based on the principle that solution properties are determined by microstructure
morphology,the composite forms of cross-linked polymer microspheres and polymers(AP–P4 and SNF3640D)in aqueous
solution are observed by the environmental scanning electron microscope(ESEM)in this paper,and the viscosity- concentration
property and viscosity shear recovery ability of the compound system are also determined. Two methods of experimental
results are reciprocally corroborated. This result preliminarily proves that there exist synergistic effects between the hydrophobic
associated polymer(AP–P4)and cross-linked polymer microspheres,and all these work would lay the foundation to further
explore the mechanism of compound system.
