| 摘 要： | 介绍了3种干扰波调查方法,给出了各种方法的优点及适用范围。在LJ地区,分别利用方形排列调查法及生产排列噪声录制法进行干扰波调查,分析了干扰波场特征,确定研究区高密度采集道距为12.5m。LJ地区高密度采集结果表明,应用干扰波调查方法以后,消除了主要干扰波的空间假频,干扰波分离效果较好,剖面的信噪比和分辨率得到了提高。 |

| Abstract: | Three kinds of interference wave investigation method were introduced.The advantages and applicability of the methods were given.In LJ area,square array investigation method and production array noise recording method were used to investigate the interference wave.After analyzing the characteristics of wavefield,the high-density acquisition trace interval in LJ area was selected as 12.5m.The high-density acquisition results in LJ area demonstrated that by using interference wave investigation methods,the spatial aliasing of main interference wave was removed and the separation of interference wave obtained good result.Meanwhile,the resolution and signal-to-noise ratio of the seismic sections were increased. |
| Keywords: | high-density seismic acquisition box wave interference wave investigation sampling density spatial aliasing |
