絮凝剂XN98处理油田聚合物驱含油污水

Study on Flocculant XN98 Treating with Oily Sewage from Polymer Flooding of Oilfield

通过筛选复配得到絮凝剂XN98，该絮凝剂由五种成分组成，其中以无机絮凝剂为主，含有少量有机絮凝剂。该絮凝剂处理油田聚合物驱含油污水效果良好，絮凝剂用量为50 mg/L时，处理后水质可以达到中、高渗透层含聚污水处理指标。絮凝剂XN98处理聚合物驱污水的药剂成本约为0.2元/t，约为PAC（聚铝）的三分之一。

Flocculant XN98 is obtained through screening and mixing. The flocculant include five components with inorganic flocculants as main component and a little organic flocculants. The Flocculant can treat oily sewage from oilfield using polymer flooding. When the dose of flocculant is 50 mg/L, treated water qualities can meet the treatment index of oil sewage with polymer from medium and high penetrating strata. The cost of flocculant XN98 treating oil sewage from oilfield using polymer flooding is about 0.2 yuan/ton, about one third of that of PAC.
