| 摘 要： | 在模拟大庆油田聚合物驱条件下,室内实验研究了高分子量聚合物的浓度、段塞组合对驱油效果的影响。实验结果表明,在聚合物总用量相同的情况下,随着高分子量聚合物浓度的增大,聚合物驱采收率增大。采用小段塞,并且不断降低聚合物黏度的方案注入时,提高采收率的幅度最大,聚驱采收率可达40.12%,最终采收率达80.48%。

| Abstract: | On the simulation of polymer flooding conditions in Daqing oil field, the effect of concentration and slug combination of high molecular weight polymer on oil displacement efficiency is studied by laboratory experiment. The experimental results show that, under the condition of the same total amount of polymer, polymer flooding recovery will increase with the increase of high molecular weight polymer concentration. Using injection scheme which is small slug and continually lowering polymer solution viscosity, the extent of improving recovery is the largest, polymer flooding recovery can reach 40.12%, and the ultimate recovery can reach 80.48%. |
