摘要
为进一步改善聚合物驱工业化区块的效果,在聚合物与碱/表面活性剂交替注入物理模拟实验研究的基础上,针对大庆油田南二区西部试验区开展了聚合物与碱/表面活性剂交替注入数值模拟研究。研究结果表明,在聚合物用量640mg/L.PV条件下,合理的碱/表活剂二元体系用量为0.2PV左右;在上述总化学剂用量相同的情况下,前置0.10PV聚合物溶液时碱/表活剂交替注入的次数以5次较佳;二元体系的注入速度对采收率的影响较小。
In order to further improve the development results of blocks for commercial polymer flooding, the numerical simulation research on the alternation injection of polymer and alkaline/surfactant in Nan2 area of Daqing oilfield was done based on the alternation injection physical simulation experimental research on polymer and alkaline/surfactant alternating injection. The research results suggested; the reasonable alkaline/surfactant volume was about 0. 2PV when the polymer volume was 640mg/L ?PV; under the same chemical volume mentioned, the relatively better number of times for alkaline/surfactant alternating injection was 5 when the preflush polymer solution was 0. 10PV; the effect of alkaline/surfactant injection rate on the recovery ratio was smaller.
