分析了油房庄油一联污水水质不能作为回注水使用的原因是污水成垢离子、细菌含量高。为此,研制筛选出成垢离子调整剂L-1和杀菌剂L-409以及其他水处理药剂;并对现流程除油罐进行改造,便于固-液分离,缩短罐内停留时间,减少细菌滋生的可能性。经新工艺配方及流程处理后的水质,各项指标均达到回注水标准;地面稳定性好,即使加热70℃、恒温24h,水质仍清亮不结垢;并与地层水具有良好的配伍性。 The reason why the water quality of Lianzhuang Oil Co., Ltd.’s joint wastewater can not be used as refilling water is that the sewage is scaled to produce ions and the bacteria content is high. To this end, the development and screening of the scale control agent L-1 and bactericide L-409 and other water treatment chemicals; and the existing process in addition to oil tank transformation to facilitate solid-liquid separation, shorten the tank residence time and reduce bacteria The possibility of breeding. After the new process formula and process of water quality, the indicators have reached the standard of water injection; ground stability, even if the heating 70 ℃, constant temperature 24h, the water is still clear and non-scaling; and formation water has good compatibility.
