| 摘要: |
| 单井注水吞吐采油是开发无能量补充小型油藏的一种有效方法，但关井平衡时间长达1年以上，经济效益较低。在注入水中加入表面活性剂和粘土防膨胀剂的全模拟对比实验结果表明，关井时间可缩短50％，并保护了储层，其采出程度可提高3．15％。 |

| Abstract: |
| Single well water-flood swallowing - spitting is a useful method for developing no energy complement small oil reservoir, but the well' s closed - in time lasts more than one year, and economic profits is lower. The paper introduces whole simulation test |
| Key words: oil production by waterflood swallowing - spitting, whole simulation test, surfactant, clay swelling inhibitor, recovery percent |
