【摘要】 报道以Ｗ／Ｏ型聚丙烯酰胺胶乳和改性氨基树脂ＴＦ－３与ＴＰＵ－１Ｌ在交联剂存在下，经适宜条件进行交联，形成互穿聚合物网络结构作为油田选择性堵水剂。实验证明，该堵水剂中增加的氨基树脂ＴＰＵ－１Ｌ与无机填料的粘结强度高于ＴＦ－３，从而提高了对水淹大缝洞的封堵强度。堵剂成胶时间适宜，耐温１５０℃，可解堵，施工方便，是目前国内强度较高的一种有机类堵水剂。更多还原

【Abstract】 A selective water plugging agent with W/O inverse polyacrylamide latex(TDG-IR)andmodified amino resin(TF-3 and TPU-IL)as major component was prepared.The prcparationand properties of the agent are introduced.It has high strength,high thermal resistance,selective characteristics for oil and water,and simplicity of production.It can be easily applied and de-plugged as well.更多还原
