摘　　要：南海东部油田大位移井作业过程中主要运用含油钻屑海上无害化处理工艺技术,该技术成功将机械除油处理工艺、电磁感应热脱附处理工艺实现海上有机集成。利用该技术对南海东部某油田两口大位移井含油钻屑进行海上回收处理,相比海上回收-陆地的处理方式,具有更为良好的应用效果:经离心分离及电磁感应热脱附处理后,钻屑含油量降至0.95%,气体排放符合国家相关标准要求。回收再利用白油约180 m^(3),并直接节省含油钻屑处理费用约500万元,达到预期效果。应用结果表明,该工艺是一种有效的含油钻屑无害化处理及油类回收利用技术,如应用于环保要求更高的一级、二级海区,将产生更高的社会效益和经济效益。The process of large displacement well in the eastern oilfield of the South China Sea of oil-containing drilling debris is mainly used,which successfully realizes the offshore organic integration of mechanical oil removal treatment process and electromagnetic induction thermal stripping treatment process.The technology is used to recover oil drilling bits from two large oil fields in the east of the South China Sea,which has a better application effect than the offshore recovery and land treatment:after centrifugal separation and electromagnetic induction thermal stripping treatment,the oil content of drilling chips is reduced to 0.95%,and the gas emission meets the relevant national standards.Recycling of about 180 cubic meters of white oil,and directly save the oil-containing drilling chip treatment cost of about 5 million yuan,to achieve the expected effect.The application results show that the process is an effective harmless treatment of oil-containing drilling chips and oil recovery technology,if applied to the primary and secondary sea areas with higher environmental protection requirements,will produce higher social and economic benefits.
