介绍以ＴＤＧ－ＩＲ和ＴＦ－３主要组份的选择性堵水剂，研究了影响堵水剂性能的有关因素。模拟油藏物化条件和现场试验证明，该堵水剂对油和水有选择性，抗压强度大，施工时基液粘度小，可携带各种固体填料，温度适应范围宽，成胶时间可调，工艺简单，有效期较长，是目前国内性能较好的一种新型堵水剂。 This paper introduces the selective plugging agent which is the main component of TDG-IR and TF-3, and studies the factors that affect the performance of plugging agent. Simulate reservoir physical and chemical conditions and field tests show that the plugging agent is selective to oil and water and has large compressive strength. The viscosity of base fluid during construction is small. It can carry a variety of solid fillers. The temperature adapts to a wide range and the gelling time can be Tune, the process is simple, valid for a long time, is currently a better performance of a new plugging agent.
