摘　　要：本文以反相乳液聚合法制得的 W/O 型胶乳代替部分水解聚丙烯酰胺水溶胶或粉剂作为油田堵水主剂,研究了影响堵荆交联时间和凝胶粘度的各种因素。结果表明,W/O 型胶乳优于水溶胶或粉剂,是一种很有前途的油田化学堵水剂。Both hydrogel and powdered products of partially hydrolyzed polyacrylamide were replaced by the products of w/o type polyacrylamide latexes prepared with inverse emul- sion polymerization which were used as the main water shutoff agent in oilfield.Vari- ous factors,such as gel-streghten and cross-linking period,have been investigated.It is shown that the w/o type latexes are superior to hydrogel and powdered products.As a new powerful water shutoff agent,it is of great prospect.
