摘要

摘要: 以海上油田水基钻井废泥浆为试验对象,采用化学固液分离法,加入不同絮凝剂脱水,并用水泥作为固化剂对脱水后的泥饼进行固化处理制成建筑材料。结果表明:钻井废泥浆经稀释后才能实现固液分离。当钻井废泥浆稀释比为4.00时,加入150 mg/kg阴离子絮凝剂A1920PAM,处理后钻井废泥浆泥饼含水率最低降至35.33%;水泥固化块中钻井废泥浆泥饼最佳加入比为25%,此时既能满足大部分建筑材料强度要求,又能大量固化钻井废泥浆;对水泥固化后的材料用水浸泡测定浸出液中主要污染物,结果显示,浸出液中COD_Cr、重金属等污染物浸出量均低于GB 8978—1996《污水综合排放标准》一级标准。

Abstract: Dehydration of waste drilling fluid from an offshore oil field was studied by adding different flocculants. Then the mud cake was mixed with cement by solidification process and made into building materials. The experimental results show that the solid-liquid separation of the waste drilling fluid can only be achieved by dilute of the fluid. The waste drilling fluid was diluted by 4 times and disposed by adding anionic flocculant A1920PAM at a dosage of 150 mg/kg, and the residual moisture content of the fluid can be reduced to as low as 35.33% after vacuum filtration. The optimal proportion of waste drilling fluid in solidified block was 25%, because the strength conditions of most building materials were satisfied and more waste drilling fluid could be solidified. After the immersion test of the solidified materials, it shows that the leaching efficiency for COD_Cr and heavy metals is below the national discharge standard.
