428XL仪器放炮常见错误的解决办法

Solution of the Common Mistakes in the Blasting of the 428XL Instrument

428XL采集系统采用SEG-D格式存储地震数据。探讨了野外地震勘探过程中,通过数据处理解决以下三个常见错误:因生产原因导致的文件号及放炮时间错误;炮点线号及桩号错误;地震道数据极性反向。实践证明,采用该方法可以保证采集数据质量,提高生产效率,避免重新打井放炮,节省成本。

The 428 XL acquisition system adopts SEG- D format to store seismic data. This article probes into the field in the process of seismic exploration,through data processing to solve the following three common problems： the file number and shooting time error; source point and source line number errors; the seismic trace data polarity error. Practice has proved that this method can ensure the quality of collected data,improve the production efficiency,avoid re-drilling and re-shooting,and saves cost.
