摘　　要： 考虑高浓度聚合物驱油条件下,聚合物各参数(尤其是黏弹性)对含水率和产油量的影响,结合喇嘛甸油田北北块的实际情况,应用前缘驱替理论,建立高浓度聚合物驱开发指标预测模型。应用该模型对喇嘛甸油田北北块一区萨Ⅲ4-10油层进行数值计算,研究了不同分子质量、注入质量浓度、注入段塞和注入速度对提高采收率的影响,并对注入参数进行优选。结果表明,在不考虑聚合物注入能力的情况下,随着聚合物注入质量浓度、分子质量、注入段塞和注入速度的增大,聚合物驱油阶段的采出程度均有所增加,驱油效率提高。 A forecast model of the development index of high concentration polymer flooding has been established by using frontal displacement theory with consideration of the impacts of polymer parameters,especially viscoelasticity,on water cut and oil production for the Beibei block of Lamadian oilfield.Numerical calculation is conducted for the SaⅢ4-10 reservoir of the Beibei block to study the influences of molecular weight,injection mass concentration,injection pore volume and injection rate on oil recovery,and to optimize injection parameters.The result shows that with the increasing of injection mass concentration,molecular weight,injection pore volume and injection rate,the recovery percent of reserves and displacement efficiency have been improved in the course of polymer flooding regardless of polymer injection capacity.
