In recent years, the node seismic acquisition technology has advanced rapidly and been widely applied in oil and gas exploration. Compared to cable-based instruments, node seismometers have outstanding advantages in terms of mobility, arrangement, and efficiency. However, they cannot acquire seismic data in a real-time manner, which poses certain challenges to quality control and data evaluation. Ensuring the quality of node seismic acquisition and maintaining the proper functioning of node seismometers have become crucial aspects during operations. In other words, it is necessary to guarantee the equipment stability and safety. Combining with field operation modes and workflows, this paper introduces the design concepts of multi-type node QC mobile App and QC data analysis platform, and discusses key technologies such as node communication, mobile positioning and navigation, node location monitoring, multi-mode inspection, data visualization, and statistical analysis. The multi-type node QC mobile App and QC data analysis platform are developed by using the Visual Studio 2022 integrated development environment and the MVC design pattern, and address the issues such as the limited generality of current node QC software and the low automation in QC data evaluation. In practical applications, the software proposed in this paper demonstrates stable performance, runs smoothly, significantly improves the QC efficiency and effectiveness of node seismometer, and effectively ensures the quality and data integrity of node data acquisition while reducing operation costs.
