大港油田免烧砖技术研究与应用

The Research and Application of Non-burnt Brick Technology in Dagang Oilfield

为合规无害化处理钻井废物,避免和降低其对生态环境的影响,针对大港油田钻井废物产生现状,对废钻井液处理后的泥浆土进行了检测分析,污染物检测结果均在GB36600-2018《土壤环境质量建设用地土壤污染风险管控标准(试行)》第二类用地管制值或筛选值范围内。采用免烧砖技术进行实验数据对比,对原料配比、产品无害化等进行分析,介绍了免烧砖制备的7个主要工艺流程,实践应用效果分析表明,利用泥浆土压制成砖,具有较好的环保效果。

The mud soil after the treatment of waste drilling fluid was tested and analyzed according to the present situation of drilling waste in Dagang Oilfield,so as to treat drilling waste in accordance with the regulations and avoid and reduce its impact on the ecological environment.The concentrations of the pollutants were all within the scope of the second category of land use control values or screening values of GB 36600-2018"Soil Environmental Quality Construction Land Soil Pollution Risk Control Standards(Trial)".The experiment data were compared by using the technology of non-burning brick,the ratio of raw materials and the harmlessness of the products were analyzed,as well.In addition,the seven major technological processes for the preparation of non-burning brick were introduced.The application of the non-burnt brick technology showed that,there is a better environmental effect by turning the mud soil into non-burnt bricks.
