摘　　要：针对马岭油田南一区地质条件,结合试验区的水质矿化度较高、硬度大等情况,初步筛选出相对超高分子质量聚合物和抗盐聚合物,并与相对中分子质量聚合物对比后进行了实验评价研究。通过对几种聚合物的理化性能、粘浓关系、稳定性及抗剪切性能研究,筛选了具有较高粘度、稳定性较好的相对超高分子质量聚合物,使其针对水质矿化度较高的马岭油田具有较好的聚驱效果。For the geological conditions of No. 1 South Block in Maling Oilfield, by integrating the facts of higher salinity and hardness of the water quality of the experimental area and so on, relatively higher molecule mass polymer and anti- salt polymer have preliminarily been screened. And furthermore comparison and experimental evaluation study of them with relativelv medium-size molecule mass polymer have been carried out. Through the physiochemical properties, viscosity-concentration relation, stability and shear resistance ability studies of the above two polymers, relatively superhigh molecule mass polymer with much higher viscosity and much better stability has been chosen and then very good polymer flooding results have obtained in Maling Oilfield with rather higher water salinity.
