摘要
针对目前多数油田存在的高含水低渗透油层特点,在电场驱替提高采收率室内研究的基础上,重点介绍了现场试验研究大功率直流电场在清除近井油层污染、提高水淹层原油产量和强化开采等方面的进展情况.结果证明:这种高效开采新技术在工艺上是可行的,具有效率高、供电设备安全性强和故障率低等特点,在增油降水提高采收率应用中前景十分广阔.
The characteristic of most present oilfields have oil layers with high containing water and low permeation. Base on the indoor research of increasing the recovery factors of oil by electric field , the article introduces mainly the progress of tests and researches in cleaning away the pollution near the wells, increasing the output of oil in containing water layers and strengthening recovery by powerful direct current electric field. The result proves that the new technology of efficient recovery is available. It has the characteristics of being efficient, high safety and low breakdown for the electrified equipments. Its foreground is very wide used to increasing oil, decreasing water ,and raising recovery factors.
