摘　　要：与传统的有缆采集相比,采用节点仪采集效率高、成本低.为适应陆上地震采集方式从有缆向节点的转变,采集数据现场处理质控技术也需要从炮域向检波点域转变.因此,本文提出了一种针对节点仪采集数据的共检波点道集的数据高效定量质控技术,首先通过炮道自动匹配精确定位技术,“先查两头、再查中间”等方式,在检波点域检查检波点和数据的完整性.然后通过共检波点道集多属性定量分析技术,对异常干扰、50 Hz工业电统计、低频异常能量统计等各类属性自动统计,质控采集数据的质量.最后,通过共检波点道集的能量、背景干扰等属性统计,对共检波点道集进行分类.本文提出的质控方法在南方复杂山地区全节点采集工区进行了应用,有效缩短了数据回收时间,提高了采集和处理效率,确保节点仪采集数据的准确可靠.Compared with traditional cable based acquisition,the use of node instruments has higher collection efficiency and lower cost.In order to adapt to the transformation of onshore seismic acquisition methods from cable to node,on-site data processing and quality control technology also needs to shift from shot domain to detection point domain.Therefore,this article proposes a real-time and efficient quantitative quality control technology for common detection point gathers collected by node instruments.Firstly,the integrity of detection points and data is checked in the detection point domain through precise positioning technology such as automatic matching of gun channels,"first checking both ends,then checking the middle",and other methods.Then,through the multi attribute quantitative analysis technology of common detection point gathers,various attributes such as abnormal interference,50 Hz industrial electricity statistics,and low-frequency abnormal energy statistics are automatically counted to control the quality of collected data.Finally,the common detection point gathers are classified and rated based on their energy,background interference,and other attribute statistics.The quality control method proposed in this article has been applied in the entire node collection work area of complex mountain areas in the south,effectively shortening the data recovery time,improving the efficiency of collection and processing,and ensuring the accuracy and reliability of node instrument data collection.
