Abstract：Quantitative analysis of seismic data quality and optimization of acquisition parameters is very important for ensuring seismic acquisition quality and improving operational efficiency. During many years' practice of exploration, BGP has studied and developed a series of quantitative analysis of raw seismic data quality and optimization of seismic acquisition parameters, for which the paper made a brief introduction and summary, including RMS amplitude quantitative estimation-based environmental noise and data QC, correlation principle-based raw record S/N ratio estimation, amplitude exponential attenuation model-based seismic record QC, linear noise separation and raw seismic record QC, spectrum shaping-based seismic record QC and parameters optimization. The techniques and methods introduced in the paper play better role in seismic acquisition data QC and parameters optimization during the seismic data acquisition.
