调剖堵水剂专用聚丙烯酰胺
 
在油田生产过程中，由于地层的非均质性，常产生水在油层中“突进”和“窜流”现象。降低油田开发效果，需要及时进行堵水调剖措施。其实质是封堵高渗透层和高产水层，调整流动剖面，以达到降低油田产水，提高最终采收率的目的。聚合物对油和水的作用具有选择性，使岩石对油的渗透率降低的少。对水的渗透率降低的多，使用时可不交联使用，也可与铝盐，铬盐等交联生成凝胶使用，还可增加某些树脂以形成互穿聚合物网络(IPN)使之具有更高耐温性。
如采用W/O型PAM胶乳和改性氨基树脂经过化学交联可以形成互穿聚合物网络堵水剂，已在油田堵水中应用并取得了明显的效果，采用PAM还可调整地层内吸水剖面及封堵大孔道，实践中已见到良好效果。
