| 摘 要： | 在分析钻井废弃泥浆组成的基础上,对泥浆体系进行稀释、酸化处理,以硅改性聚合氯化铁为破胶剂,阳离子聚丙烯酰胺为絮凝剂,破坏钻井废弃泥浆的胶体体系,采用固液分离方法使泥浆液混凝脱水。试验表明:稀释倍数为4倍、pH值为5、2.5%改性聚合氯化铁为破胶剂、0.25‰阳离子聚丙烯酰胺为絮凝剂、0.8%N-626为去油剂,离心分离后泥饼中石油类含量低于3‰,混凝产生的絮体大、脱水率高、残渣稳定性好、无造浆能力。

| Abstract: | On the basis of compositional analyses of oil-bearing waste drilling mud,waste mud system was diluted and acidified.Acting as gel breakers and flocculants respectively,silicon modified polymeric aluminum chloride and cationic polyacrylamide can completely destroy the colloidal system of oil-bearing waste drilling mud.Then waste mud is concreted and dewatered by solid-liquid separation.The results show : diluted ratio 4,pH=5,2.5% modified polymeric aluminum chloride as gel breakers,0.25‰ cationic polyacrylamide as flocculants,0.8% N-626 as degreaser,the petroleum content of the filter cake is below 3 after centrifugal separation and it has better dewatering performance. |
