| 摘 要： | 注入水改性技术是通过离子调整的方法 ,去除水中的CO2 和HCO-3 ,使水质由弱酸性变为碱性。改性处理后的水不仅提高了水质 ,减缓了腐蚀和结垢 ,降低了污水处理成本 ,减少了对环境的污染 ,而且还改善了注水井的吸水状况 ,增加了油田水驱动用储量。该文简要介绍了中原油田注入水质改性技术的现场应用情况 ,研究了改性注入水对油田注水开发的影响 ,对今后进一步提高和完善污水处理工艺 ,改善油田开发效果 ,具有重要意义。

| Abstract: | Injected water modification technology is to remove CO 2 and HCO 3 - from water by ion adjustments in order to make water quality turn from mild acidity to basicity. Having been modified, water was slowed down corrosion and scale buildup and reduced treatment cost and environmental pollution. Also, water absorbing condition of injection well was improved and waterflooding producing reserves of oil field were increased. This paper introduced the field application of injected water modification technology in Zhongyuan oil field. The influence of modified injected water on waterflooding is studied. It's significance for improving wastewater treatment technology and development efficiency of oil field in the future. |
