摘　　要：为降低普光气田1#水处理站水处理系统硫化氢泄漏风险,提高药剂利用效率,确保注水水质合格,采取了增设pH值调节剂加注系统控制来水pH值以提高气浮除硫效果,调整除硫剂加注口位置降低气浮池硫化氢含量以降低硫化氢泄漏风险,增设污水缓冲罐控制来水平稳性,增设药剂混合器增加药剂混合反应时间,增设p H值和悬浮物在线监测仪时时监测水处理状态等措施。上述措施控制了来水平稳性,实现了药剂加注的自动化控制,提高了药剂的利用效率,泄漏和环境污染问题得到了有效控制,处理后的污水水质达到了油田注水的标准。In 1#water treatment station,Puguang Gas Field,a pH value regulator system was added to improve the gas flotation sulfur removal effect so that the p H value of supplied water was under control.This act reduced the risk of hydrogen sulfide leakage,improved the chemical efficiency and ensured the injection water quality.Meanwhile,the entrance of sulfur removal agent was adjusted to decrease the content of sulfide hydrogen,which helped to lower gas leakage risk;a waste water buffer rank was introduced to control stabilization of incoming water;a agents mixer was used to prolong the reaction time;an online monitor of p H value and suspended matter was newly available to monitor the water treatment condition.All these acts above took the control of the automatic chemical filling and improved the performance efficiency of the chemical.Thus,the hydrogen sulfide leakage risk and environment pollution are under control,and the quality of the waste water met the standard of water injection in oilfield.
