摘　　要：在目的层埋藏极浅地区采用小道距观测系统,在弯线施工中缩小CDP面元的大小,放大地质现象,使地质现象反映更为清晰,在实际施工中取得了较好的地质效果。The geometry of small trace interval was used in the area where the goal coal layer buried extremely shallow, which narrowed the size of the CDP cell in the curved surface line, the enlarged geological phenomenon, made the geological phenomenon more clearly, and finally vet good geological effects in act.

关 键 词：小道距 CDP 叠加 接收 信噪比 地震勘探
