本文简要介绍了柔性聚合物在低渗透多孔介质中的桥堵吸附机理 ,并且应用Zitha和 Btermans的油藏实验模型和结果对桥堵吸附作用进行了验证 ,详细论述了影响桥堵吸附的作用因素以及在低、中渗透层中增加桥堵吸附作用的方法 ,最后提出对中低渗透率的油藏特别是难以区分的薄油层 ,水平井的堵水作业 ,可以利用聚合物的固有性质 ,不使用层间隔离直接作业 ,这样可以大大降低生产成本 ,节约作业时间 In this paper, the mechanism of bridging adsorption of flexible polymers in low-permeability porous media is briefly introduced. The adsorption experiments of bridging plugging with Zitha and Btermans reservoir models are validated. The influencing factors of bridging plugging adsorption are discussed in detail. And the method of increasing the bridging plugging adsorption in the low and middle permeable layers. Finally, the paper puts forward the water plugging operation of the reservoirs with medium and low permeability, especially the indistinguishable thin oil reservoirs and horizontal wells, which can utilize the intrinsic properties of the polymer and not Direct use of interlayer isolation operation, which can greatly reduce production costs and save time
