Visualization Research of Polymer Microsphere Profile Control and Flooding Mechanism

Visualization model is an important means to study the mechanism of polymer microspheres. In this paper, the self-made capillary model, micro-pore throat glass plate model and frosted glass oil displacement model are used to visualize the expansion, plugging and displacement performance of polymer microspheres. On this basis, the displacement mechanism of polymer microspheres is analyzed and discussed. The experimental method and the visual experimental model established in this paper provide a new method for studying the mechanism of polymer microsphere profile control and flooding.
