摘要：

Conventional methods for seismic data acquisition quality control such as first-breaks on the minimum 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. © 2018, Editorial Department OIL GEOPHYSICAL PROSPECTING.
