Abstract：Conventional methods for seismic data acquisition quality control such as first-breaks on the mini-mum offset,linear correction,and common shot-point/receiver-point gather stacking are manual methods.They hardy have a unified standard and miss the quality-control of some shots due to visual fatigue.On the other hand,a daily production may nowadays reach tens of thousands of shots in the present seismic high-productivity acquisition.These conventional methods cannot complete the quality control for so many shots of seismic data.In this paper,we propose a 3σ standard detection of shot-point/receiver-point offsets based on the research of the above-mentioned methods.This approach detects automatically delays between the reference and common shot-point/receiver-point gather stack linear corrections,and a detection report is achieved.The proposed approach can not only improve greatly the efficiency of seismic data acquisition quality-control,but also avoid missing the quality-control of some shots.
