【 摘 要 】

A block and B block are two weak base alkali-surfactant-polymer (ASP) flooding blocks. These two blocks have received a good effect by enhancing oil recovery over 20 percent. Based on depth analysis of the dynamic variation rule of these two blocks, summarize the exploitation characteristic, such as the injection-production capability, the section exploitation, produced chemical agents feature and scaling situations. It is concluded that the weak base ASP flooding is more suitable for industrial promotion owing to its strong injection and production ability and light scale degree. The understanding can be used for reference for the follow-up promotion of the weak base ASP flooding.
