摘　　要：以氚水和35S作为示踪剂进行的监测结果表明,边水垂直于等高线由外向内连续侵入,在边部中间其侵入速度大于边部两边;通过室内试验,对堵剂构成和施工参数进行优化,利用超细水泥-粉煤灰进行稠油油藏边水封堵现场实验,对延缓边水内侵起到了积极作用,同时具有一定的增油效果,但不能阻止边水内侵。Taking tritium and ^35S as the tracer, the inspecting result shows that the margin water intrude continually from outside plumb to contour. The speed in midst is quicker than in two sides. After indoor test and optimizing plugging substance composing and construction parameter, it has active affection to stave the margin water to plug with super-thin cement and dusty coal ash in heavy oil reservoir. Margin water plugging also can increase production, But it can＇t stop the margin water.
