用亚硫酸盐作为前置预处理液，加快丙烯酰胺-甲叉基双丙烯酰胺地层内聚合堵水，这是一种新技术。加入亚硫酸盐，可使丙烯酰胺-甲叉基双丙烯酰胺体系反应时间加快，对堵剂溶液和凝胶强度基本没有影响。利用该技术堵水封窜，可大大节约堵剂用量，并提高封堵成功率。该堵水技术的堵剂现场配制、地层内聚合，堵剂用量少，施工工艺简单。现场堵水试验结果表明，该堵水技术简单易操作，堵水成功率高，对封堵管外窜槽尤其有效。
Using sulfite as a pretreatment solution to accelerate the polymerization of acrylamide - methylidenebisacrylamide formation blocking water, which is a new technology. Addition of sulfite can accelerate the reaction time of acrylamide-methylidenebisacrylamide system and have no effect on the solution of plugging agent and the strength of gel. Use of the technology plugging water channeling, can greatly save the amount of plugging agent, and improve the success rate of closure. The plugging water blocking technology site preparation, formation polymerization, blocking agent with less, the construction process is simple. The results of on-site water plugging test show that the plugging water technology is simple and easy to operate, has a high success rate of water plugging, and is particularly effective for channeling the plugging pipe outside.
