Overview of Methods of Improving Oil-gas Recovery Efficiency by Chemical Flooding |
| |
| Abstract: | How to improve oil-gas recovery efficiency is always a topic explored in oil industry all over the world, in particular when reservoir development enters into high water cut period. The primary technologies of improving oil-gas recovery efficiency include chemical flooding, gas flooding and thermal recovery. In China, we are enlarging the scale of chemical flooding gradually and going into the large-scale application. In this paper, three methods of chemical flooding were summarized, and major problems and development trends of chemical flooding were analyzed combined with the international existing experiences. |
