摘要
大庆油田二次采油后还有很多含剩余油油藏,针对这种油藏进行三元复合驱室内实验研究,实验结果表明,二次采油后进行三元复合驱油即碱/表面活性剂/聚合物对原油的采收率有明显的提高。其中聚合物浓度以及表活剂浓度对剩余油开采都有着重要的作用,通过调整聚合物浓度,表面活性剂浓度对采收率的影响从而确定合理的开采浓度进一步提高油田剩余油的采收率。
There are many containing residual oil reservoirs in Daqing oilfield after secondary recovery. In this paper, laboratory experiment of ASP system in remaining oil reservoirs was carried out. The experimental results show that the ASP system of alkali/surfactant/polymer has significant effect on enhancing oil recovery after secondary recovery. The polymer concentration and surfactant concentration have important effect on the remaining oil development, suitable polymer concentration and surfactant concentration can further improve the recovery of residual oil.
