冀东高尚堡油田采油污水处理技术研究

Techniques for Produced Sewage Treatment in Jidong Oilfield

分析了高尚堡油田采油污水的化学成分,研究了药剂除油和固体悬浮物的效果,优选复配出水处理效果好的药剂FSAN。同时研究了处理后水与地层水的配伍性,并进行药剂现场试验。结果表明,新的水处理药剂FSAN在不改变原采油污水处理工艺的情况下,可使处理后的水质既可达到注入水水质标准,又可达到外输水质标准。

The chemical composition of sewage produced in Gaoshangbao Oilfield is analyzed.The effects of deoil by using agent and suspended solids are studied.Selected FSAN is of good combination effects of produced water processing,the compatibility of treated water with formation is studied and field test is conducted on the treating agent.The result indicates that the quality of treated water can meet the water quality standard and drained water standard by using the new FSAN without changing the sewage treating process.
