摘　　要：针对胜利海上埕岛油田化学驱用的聚合物,开展了不同浓度聚合物溶液在不同注入流量下分别通过常规金属毡、憎水金属毡、绕丝等6种类型滤砂管后的聚合物溶液剪切粘度保留率试验。结果表明,在满足矿场挡砂精度要求的前提下,与常规金属毡、憎水金属毡滤砂管相比,精度为0.1mm的绕丝筛管的聚合物溶液剪切粘度保留率最高,平均可以达到96%以上;在同等精度下,表面为憎水材料的金属毡滤砂管的聚合物溶液剪切粘度保留率明显优于常规金属毡滤砂管;结合海上特殊的矿场条件,推荐采用涂覆憎水金属毡滤砂管。In order to study the polymer used for chemical displacement in Chengdao Oilfield of Shengli Oilfield,experiments were performed to study the shearing retention rate of different concentrations of polymer fluids flowing through ordinary metal felt,hydrophobic metal felt,wrapping wire and other three types of screens under different injecting flow rates.Experiments results show that based on precision of sand barrier,the field sand retention accuracy demand is satisfied with oilfield requirements compared with ordinary metal felt and hydrophobic metal felt,the shearing retention rate of polymer fluid flowing through wire wrapped screen with 0.1mm accuracy is the highest,average value is more than 96%.Under the same accuracy,the viscosity retention rate of hydrophobic metal felt screen is much higher than that of ordinary melt felt screen.In combination with special offshore oilfield conditions,coating hydrophobic metal felt screen is recommended.
