Abstract：On-site QC is a necessary means to ensure the quality of marine towed cable seismic acquisition and improve production efficiency. Through timely acquisition of the status information of each system recorded in SEG-D or SEG-Y files, and displaying it in a flexible and intuitive way, the acquisition status and data quality can be monitored in real time. At the same time,in order to adapt to the characteristics of large amount of data and conti-nuous marine towed cable seismic acquisition, the working status of the equipment such as cable and gun array is automatically monitored in real time, and various data are displayed in real time, including single shot record, near-trace section, stacked shot gather, stacked common cable data, near-field geophone, TB signal and RMS amplitude, to ensure the quality of seismic data and reduce costs. The practical application shows that this method can effectively monitor the air leakage, self excitation and pressure change of air gun, the noise development of cable, the quality of recorded seismic signals, and the abnormalities of seismic amplitude and frequency. Problems can be found in real time and solved quickly. This saves the working time of the fleet and improves the construction efficiency.
