摘　　要：随着油气资源需求的日趋增加,勘探难度不断加大,推动了当代地震采集设备的技术进步,新一代无线、单点节点仪器系统正在加快脚步替代传统有缆仪在可变观测系统、高道数、高覆盖次数的油气勘探项目中使用。鉴于此,立足于新的SCRXYB三维地震勘探项目,分别从施工前设备调研、对比试验、尽职调查,施工中节点仪标准化埋置、过程质量控制、质量反馈与跟踪、质量评比与奖惩,施工后设备回收、数据整理、总结评价等方面进行了节点仪状态及埋置质量控制方法的总结,由此在SCRXYB三维施工中取得了节点仪一次埋置合格率提升、埋置质量整体提升、施工效率提升、数据准确率提升等显著成果,形成了一套详细、完善且具南方复杂山地采集特色的节点仪状态及埋置质量控制方法。As the demand for oil and gas resources continues to grow,the difficulty of exploration is constantly increasing,which promotes technological advancements in contemporary seismic acquisition equipment.A new generation of wireless,single-point node instrument systems is accelerating to replace traditional cable instruments in variable observation systems,high-channel-count,and high-coverage oil and gas exploration projects.In light of this,based on the SCRXYB 3D seismic exploration project in 2022,this paper summarizes the control methods for the status and embedding quality of node instruments from various aspects,including pre-construction equipment research,comparative testing,and due diligence;standardized embedding of node instrument during construction,process quality control,quality feedback and tracking,quality evaluation,and reward and punishment;and post-construction equipment recovery,data organization,and summary evaluation.As a result,significant achievements were made in the SCRXYB 3D construction,including an increase in the first-time embedding qualification rate of node instruments,an overall improvement in embedding quality,an increase in construction efficiency,and an improvement in data accuracy.A set of detailed,comprehensive,and characteristic node instrument status and embedding quality control methods suitable for the complex mountainous terrain of the south has been established.
