乍得水基钻井废弃物处理技术研究及应用OA
Research and Application of Water-based Drilling Waste Treatment Technology in Chad
乍得要求石油勘探开发过程中所产生废弃钻井液的主要污染物指标满足ISO国际标准.乍得水基钻井废弃物采用机械离心及化学破胶絮凝方法将其分离为固相和液相,而后分别进行针对性的处理研究和实验,对固液分离产水采用电化学氧化、气浮浮选、超滤及反渗透膜进行深度处理,终端产水COD综合去除率达 98.29%.剩余固相固化处理后,固化体浸出液相关指标如色度、石油类含量、COD、氨氮及重金属离子浓度,均达到GB/T 8978-1996《污水综合排放标准》一级标准.乍…查看全部>>
Chad has put forward strict requirements for the main pollutant indicators of waste drilling fluids generated during the oil exploration and development process meet the ISO international standards.The Chadian water-based drilling waste treatment technology refers to the waste treatment technology that focuses on non landing reception,dehydration and reduction separation,deep water treatment,and residual solid solidification treatment as key technical nodes.…查看全部>>
