摘要
为了在二元复合驱油过程中,既取得增油效果,又达到节约化学剂用量和减少污染的目的,利用不同采出阶段采出液及其配制的二元复合体系,进行了采出液二次利用驱油的物理模拟实验。将采出液原样、采出液原样配制的二元复合体系、深部处理污水配制的二元体系这3种试剂进行驱油效果对比。结果表明:使用采出液原样配制的二元复合体系的驱油效果与深部处理污水配制的二元复合体系驱油效果相当,优于直接使用采出液原样。
Physical simulation experiments have been conducted for a surfactant/polymer(SP) flooding system prepared with produced liquid for secondary utilization in order to improve oil recovery,save chemicals and reduce pollution.The oil displacement results of 3 agents are compared,including original produced liquid,SP system prepared with original produced liquid,SP system prepared with in-depth treated produced water.The results indicate that the oil displacement results of SP systems prepared with original produced liquid and treated produced water are similar and superior to only using original produced liquid.
