摘要
聚合物控水采气技术 ,是采用VS/VA/AM三元共聚物或HPAM共聚物和PAM聚合物 ,在气藏岩石表面形成选择性阻挡层 ,有效阻止地层水的流动 ,达到有水气藏控水采气的目的。文中介绍了聚合物制备、控水原理及堵水采气方法 ,重点介绍VS/VA/AM三元共聚物 ,其堵水效果高于其它聚合物。
The technology of polymer control water gas production which adopts VS/VA/AM three-part copolymer,or HPAM copolymer and PAM polymer to form a selectivity barrier layer on the rock surface,can effectively prevent the formation water flowing,and achieve the goal of control water gas production in water-bearing gas reservoir.The paper presents the preparation of the polymer,and the principle and methods of polymer control water gas production.Through analysis,the water plugging effect of VS/VA/AM three-part copolymer is better than the other polymers.
