| 摘 要： | 通过一系列室内实验,对振动增加采收率的机理进行了详细的研究。使用人造岩心、天然露头砂岩岩心,天然油田砂岩岩心及模拟油进行了驱替实验。实验表明,机械振动可提高岩心水驱油的无水采收率及最终采收率,可推迟见水,降低岩心残余油饱和度。

| Abstract: | The Mechanism of vibration increase productivity is studied in detail by means of a series of laboratory experiments. The displacement experiments were made by using artificial core, natural outcrop sandstone core,natural sandstone core in oil field and simulated oil. The results of these experiments show that by using mechanical vibration, the waterflood water-free oil recovery factor and the final recovery factor of the cores can be increased, the water breakthrough can be postponed, and the residual oil saturation of the cores can be decreased. |

| Keywords: | machinary vibration increase productivity core recovery factor water drive residual oil saturation |
