The experiment being made by our research is focusing on preparation and characterization of expandable plugging agent. This kind of heat resident plugging agent with spherical shape was synthesized by emulsion polymerization based on acrylamide (AM), acrylic-acid (AA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS). 2,2'-Azobis (2-methylpropionamide) dihydrochloride (AIBA) as functional catalyzer. Further separation and purification of the extracted products will be carried out to obtain the ideal products. The chemical and morphology of resin is investigated by means of thermogravimetric analysis (TGA) and scanning electron microscopy (SEM), respectively. Moreover, compared with typical plugging agent, the expandable plugging agent we prepared should demonstrate superior properties on the aspects of temperature resistance.
