摘　　要：目前,我国大多数注水开发的油田已进入高含水开发阶段,堵水调剖技术得到了广泛应用。本文论述了通过物模试验,开展水膨体类调剖剂对孔隙的封堵能力、封堵强度等研究,探索水膨体类调剖剂在地层中的封堵机理,对高含水油田合理应用水膨体类调剖剂提供参考。Most of China＇s water-flooding oilfields have entered the stage of high water-cut development, and the water shut-off and profile-control technologies have been applied widely. By conducting physical model experiments and by studying the shut-off capacity and intensity of swellable profile-control agents on pore, this paper explores the shut-off mechanism of swellable profile-control agents in strata, and provides some reference on reasonable application of swellable profile-control agents into high water-cut oilfields.
