| 摘 要： | 广角反射条件下深层地震记录的信噪比较高，获得的地震资料质量较好，因此广角反射勘探方法是复杂地 表区地震勘探的一种有效方法。根据广角反射理论，分析了实际地震采集中不同炮检距广角反射对地震资料的 影响，获得了适合于ＹＭ １区块地震采集的炮检距。与以前的地震剖面相比，新剖面上地震反射波组的能量、信 噪比及连续性均有明显改善。

| Abstract: | With wide angle reflection seismic acquisition,high signal-to-noise ratio deep seismic data can be recorded.Therefore,wide angle reflection seismic is an effective seismic acquisition method in areas of complex mountainous terrain.With wide angle reflection theory,we investigated the effect of different offsets on seismic data quality,and determined the optimal offset for seismic acquisition in working area YM-1.Compared to legacy data,the newly acquired data is superior in reflection energy,S/N ratio,and event continuity. |

| Keywords: | wide angle reflection signal-to-noise ratio offset |
