聚磺钻井岩屑制备烧结砖环境风险分析
Environmental risk analysis of sintered bricks prepared from sulphonated polymer drill cuttings
摘要
Abstract
Objective Taking the sulphonated polymer drill cuttings from the drilling process in the Sichuan Basin as the research object,analyzed the contamination characteristics of the remaining solid phase after curing treatment or glue-breaking flocculation+mechanical separation.Tthe environmental risk of sintered bricks prepared using the sulphonated polymer drill cuttings as also evaluated on this basis.Methods The Texas model and HJ/T 299-2007 Solid waste-Extraction procedure for leaching toxicity-Sulphuric acid&nitric acid method were used to study the pollution characteristics of the remaining solid phase and the environmental risk of preparing sintered bricks after curing,flocculation and mechanical separation of sulphonated polymer mud drilling waste.Results The content of heavy metals zinc and barium in the pre-treated polysulfone drilling waste is relatively high.As a raw material for the preparation of sintered bricks according to a certain mixing ratio of the process of emission of non-methane hydrocarbons in the flue gas emission,the mass concentration of 2.4-23.7 mg/m3 for heavy metals,and dioxin emissions are also much lower than the requirements of the GB 16297-1996 Integrated emission standard for air pollutants,GB 18484-2020 Standards for pollution control on hazardous waste incineration,GB 30485-2013 Standard for pollution control on co-processing of solid waste in cement kiln,and the leachable heavy metal content of the sintered bricks is also lower than the limit of ClassⅢstandard of GB/T 14848-2017 Standard for groundwater quality.Conclusion The overall environmental risk of using sulphonated polysulfone drilling waste as raw material for preparing sintered bricks is manageable.Researching on the environmental risk assessment of sintered bricks prepared from sulphonated polymer drill cuttings,the results of which can provide a theoretical basis for the revision of national policy documents and help the environmental management department and oil and gas development enterprises to reduce costs and increase efficiency,as well as promote the green and high-quality development of China's oil and gas sources.关键词
