Plugging Mechanism of Cross-linked Polymer Microspheres for Profile Control
In the study presented in this paper, the shape, size and deformation of cross-linked polymer microspheres were observed using a scanning electron microscope (SEM) and a light microscope.A capillary flow experiment, micro-visual model, nuclear-pore film filtration experiment and sand-packed model were utilized to explore the plugging mechanism of microspheres in porous media.The results demonstrated that the microspheres typically had a spherical original shape with a size ranging from a few microns to tens of microns.When the microspheres were dispersed in water, they became larger due to swelling, at a range of 10 to 100μm.
