废弃钻井液无害化处理技术的研究

摘要

The major ingredient of mud was polyacrylamide , sodium carboxymethyl cellulose , sulfonated asphalt ,no fluorescence lubricants and so on .It has the high viscosity ,high concentration of organic matter and pollutant characteristics .It may quickly solve the stability of the mud system by chemical treatment technology.The results show that polyacrylamide degrading HK 618, demulsifier HK201 and catalyst HK458 could make waste drilling fluid rapid degradation hydration for 2 h.It achieve the complete sepa-ration of solid phase ,water and oil .Adopting the new technology can solve the stability problem of drilling fluid viscous material .It has the vital significance for the future ecological restoration .%延长油田应用的泥浆主要成分为聚丙烯酰胺、羧甲基纤维素钠等，具有粘度高、有机物浓度高、污染物种类多等特点，加入研制的聚丙烯酰胺降解剂HK618、破乳剂HK201和催化剂HK458，可以使其2 h内快速降解水化成小分子，实现固相、水、油的完全分离。采用新技术能够解决传统化学处理中钻井液废弃物粘稠物质的稳定性问题，对未来生态恢复也具有重要的意义。
