摘要：Weak base ASP flooding is an important technique to replace oil production. Field tests show that weak base ASP flooding achieves the good effect of EOR 18% in classIIreservoir, and has many other advantages such as strong injection-production capacity, high production speed and oil increasing multiples, light scaling and emulsion level and easy to clean. It has a broad prospect. This paper analyzes the changing characteristics of weak base ASP flooding injection-production capacity, compares two types of polymer flooding blocks with similar reservoir conditions, identifies key factors affecting injection-production capacity and provides insights for future development of weak base ASP flooding in classII reservoirs.
