摘　　要：针对华池油田H联合站站内采出水“一级沉降除油+一级过滤”处理工艺,通过室内优选除油剂和絮凝剂,利用协同增效机理,复配得到了适合该油田采出水处理的高效复合净水剂JS-Ⅰ,并进行了工业生产。结果表明:自制的除油剂A-1除油效果好于其它类型除油剂,将该除油剂与优选出来的絮凝剂B-2按质量比45∶55复配得到高效复合净水剂JS-Ⅰ;JS-Ⅰ加剂量200 mg/L、温度30℃、沉降时间2 h的条件下,污水中固体悬浮物和油分含量分别从原来的251.2,346.8 mg/L降低至21.5,27.8 mg/L;现场试验表明,JS-Ⅰ处理后的污水经压力过滤后,污水中固体悬浮物和油分含量分别降低至15.0,18.0 mg/L以下,达到回注水水质要求。According to the treatment process of"first stage sedimentation oil removal+first stage filtration"for produced water in H combined station of Huachi oilfield,through optimizing the oil removal agent and flocculant following the mechanism of synergism,a high-efficiency composite water purification agent JS-1 suitable for the treatment of produced water in this oilfield was prepared and manufactured in industry.The results show that the oil removal effect of self-made oil remover A-1 is better than that of other types of oil removers,and the high-efficiency composite water purification agent JS-1 can be obtained by mixing the oil remover with the optimized flocculant B-2 according to the mass ratio of 45∶55;under the condition of adding dose of 200 mg/L,at 30℃,settling time of 2 h,the content of solid suspension and oil in the sewage can be reduced from 251.2 and 346.8mg/L to 21.5 and 27.8 mg/L,respectively.The field test shows that the content of solid suspended matter and oil in the sewage after JS-1 treatment is reduced to below 15.0 and 18.0 mg/L,respectively,after pressure filtration,which meets the requirement of reinjection water quality.
