摘要

碱-表面活性剂-气体交替注入(ASAG)是一种提高采收率的方法。在WAG工艺的注水阶段，将化学品(碱性表面活性剂)添加到堵头中。本文在油藏尺度上进行数值模拟研究，分析ASAG过程对提高采收率的影响因素。研究结果表明，ASAG工艺的最终采收率可达67%，比水驱提高约22%。在各种影响因素中，注入速度、堵塞体积和化学药剂浓度对采收率影响较大。

Numerical Simulation of Alkali-Surfactant-Alternated-Gas(ASAG) Injection: Effects of Key Parameters

Alkali-surfactant-alternated-gas (ASAG) alternating injection is a method used to enhance oil recovery. In the water injection stage of the WAG process, chemicals (alkaline-surfactant) are added to the plug. This paper presents a numerical simulation study at the reservoir scale to analyze the influencing factors of ASAG process on improving recovery efficiency. The research results indicate that ASAG process can achieve an ultimate recovery efficiency of 67%, which is approximately 22% higher compared to water flooding. Among the various influencing factors, injection rate, plug volume, and chemical concentration have a significant impact on the recovery efficiency.
