摘　　要：本文报导了由W/O乳液型聚丙烯酰胺TDG-IR+交联剂和改性氨基树脂TF-3+固化剂形成的互穿聚合物网络堵水剂现场应用试验,介绍了选井原则、堵剂配方和施工工艺,通过典型井例说明了施工效果。The novel water-shutoff agent of gelling interpenetrating polymer network(IPN) type is composed mainly of PAM in W/O emulsion(TDG-IR) and crosslinker, modified amino resine(TF-3) and curing agent and has been put into field tests in Huabei Oil Fields. The criteria of well choosing, the work formulation desining and the use of reinforcement and filler in the system in particular, and the technology of performing water shutoff operations are described in detail. The field tests in 13 producing wells in two blocks are illustrated and some examples discussed.
