河南双河高温油田三元复合驱实验研究

LABORATORY STUDY ON THE ASP FLOODING IN THE HIGH TEMPERATURED SHUANGHE OILFIELD IN HEHAN

在 75～ 85℃的高温条件下 ,针对河南双河油田油水特点筛选出了界面张力性能优异的碱 表面活性剂 聚合物三元体系配方 ,并对该配方的热稳定性、岩心驱油效果等进行了研究。

Under the condition of the high temperature of 75-85℃, an alkali surfactant polymer system ingredient with a nice performance of interfacial tension is selected according to the oil and water characteristic of Shuanghe in Henan, the heat stability and core displacement effect of this ingredient is studied.
