摘　　要：针对川渝地区废弃钻井液固化处理简单,固化物浸出液多项指标达不到污水排放标准的问题,采用水淬高炉矿渣作为固化主剂代替水泥,对2口井的废弃聚磺钻井液进行了固化试验。结果表明:钻井液固化后,其固化强度和浸出液指标都达到要求,做到无害化处理,而且工艺简单,成本低,现场应用取得较好的效果。分析了高炉矿渣的固化机理。In Chuanyu area,the simple solidification of the waste drilling mud produced condensate having leachate unable to reach the criterion for sewage discharge.A blast furnace slag was substitutes for cement as solidification chemical to treat the waste polymer-sulfonate mud in two wells.It was shown that the solidified mud had enough solidification strength and the leachate of the solidified mud reached the criterion for sewage discharge.This lowcost technique is simple,and field practice proved successful.A mechanism of this technology is also hypothesized in this paper.
