Abstract: By the analysis polymer infection wells plugging,the plugging remover ZM - 1 was synthesized with epichlorohydrin and polyethylene polyamines as the main starting materials.The reaction process was studied and the result as follows,the feeding ratio:n(diethylenetriamine)/n(epichlorohydrin)=2.5∶1.0,the reaction temperature is 60 ℃,the reaction time is 6 h.The performance of plugging remover was studied through the core simulation experiment in the room. The experiments show that the plugging remover ZM-1 has effects obviously for the problem of polymer infection wells plugging of Daqing oilfield.The percent of plugging remover can reach 94.2%.
