Abstract: The Fe2+, S2- and bacteria existed in polymercontained sewage can degrade polymer solution, resulting reduction of oil displacement efficiency. In this paper, three kinds of treatment technology, oxygen exposure, sterilization and combination of oxygen exposure and sterilization, are used to deal with polymercontained sewage, then the dealt polymercontained sewage is used to dilute polymer solution. By measuring viscosity of diluted polymer solution, the impact of three kinds of treatment technology on viscosity is analyzed. The reasonable treatment technology is determined, which provide beneficial theoretical support for ensuring the stability of polymer solution viscosity and enhancing oil recovery.

摘要: 含聚污水中所含的Fe2+、S2-等还原物质和细菌,对聚合物溶液有降解作用,影响聚合物溶液的驱油效果。利用曝氧、杀菌及曝氧与杀菌相结合3种处理技术对含聚污水进行处理,再用处理过的含聚污水稀释聚合物溶液,测量稀释后聚合物溶液黏度的变化,分析曝氧和杀菌对含聚污水稀释聚合物溶液黏度的影响,并确定合理的曝氧和杀菌处理技术,为保证聚合物溶液黏度的稳定性、提高油田采收率提供有利的理论技术支持。
