چکیده مقاله:
Acrylamide microspheres are synthesized by an inverse suspension copolymerization. Acrylamide is used as monomer, and N,N’- methylenebisacrylamide as a crosslinker polymerized by a redox system intolouene, each emulsified by a series of sorbitan surfactants. Themicrospheres had a well size distribution, and swelling and rheologicalproperties. the performance of these microspheres in propagation throughporous media is evaluated using two dimension glass micromodel. Theimages confirmed that the microspheres can improve the oil displacementin oil reservoirs, and can be used for in depth fluid diversion as aconformance control methods. It was found that microspheress were stable in brines with ٦٠,٠٠٠ ppm salt at ٨٠ oC for ٦ months.
