摘要
通过岩心驱替试验,评价了hyz-5表面活性剂对中性致密砂岩循环注水采收率的影响。试验表明,在对hyz-5型表面活性剂溶液进行周期性注水后,产量明显增加,说明在致密砂岩油藏中,表面活性剂可以提高致密油藏的渗透率。
through core displacement test,the effect of hyz-5 surfactant on cyclic water injection recovery of neutral tight sandstone was evaluated.Field tests show that the production of hyz-5 surfactant solution increases significantly after periodic water injection,which indicates that surfactant can improve the permeability of tight sandstone reservoirs.
