复杂地表条件地震勘探施工设计
|
摘要
复杂地表的地震勘探施工设计一直是野外施工的难点。本文通过对复杂地表工区内详细踏勘,针对复杂地表环境选取有代表性的试验点,确定激发参数,合理分布表层结构调查点位,综合分析,最后采取避高就低,避沼泽河流的淤泥带以及避水陆淤泥过渡带等办法,在施工过程中很好的解决了地表一致性差和表层结构复杂这一难题,现场监控剖面波组同相轴连续性好,信噪比高,取得良好的勘探效果。
It is always difficult to design the seismic exploration construction work in the complicated surface.After the work area scouting,we selected the representative test points in view of the complicated surface,determined the shooting parameter,distributed the surface investigation points in reasonable,analysis and adopted some methods like evading the high place,evading oozy of the swamp and rivers and so on.In this way,the construction work has solved the problem about complicated surface,the section of the on-site processinghas a highsignal-to-noise ratio and the composite wave continuance,acquired result very well.
