This study shows that for improving development effect in the cyclic flooding, order of roles played by various forces are: capillary force, elastic force, while gravity plays no part in it basically.
Cyclic water injection development can expand sweep radius and enhance displacement efficiency.
通过多周期的注水吞吐开发，逐渐扩大水驱波及半径，提高驱替效率。

Abdominal distention, due to the development of ascites, may be detected only by a change in belt size, and it may be intermittent, related to cyclic alcohol intake.
