摘　　要：南海某井在起钻过程中发生中子源落井事故,选择和使用专用打捞工具,结合对井下情况的判断、测井仪器的结构分析等,制定了一系列的处理措施和方案,成功将放射源打捞出井。该文通过对打捞放射源过程的分析,提出打捞大位移井放射性源的关键步骤和措施,给今后类似复杂情况处理提供参考和借鉴。A well in South China Sea had a neutron source falling accident during the drilling process.A series of treatment measures and schemes were formulated by selecting and using special fishing tools,combining with the judgment of downhole conditions and the structural analysis of logging tools,and the radioactive source was successfully salvaged out of the well.Based on the analysis of the process of salvaging radioactive sources,this paper puts forward the key steps and measures of salvaging radioactive sources in large displacement wells,and provides reference for similar complex situations in the future.
