摘要
砖墙式三维观测系统是一种较为特殊的观测系统 ,与常规的规则束状观测系统相比 ,它具有使炮检距、方位角等分布更加合理的特点。这种观测系统在国内尚未得到应用和推广 ,而在国外则得到较广泛的应用。本文就砖墙式三维观测系统的特点进行了详细分析 ,并结合在委内瑞拉Caracloes三维工区的实际应用情况进行了总结 ,实际获得的资料信噪比高、层次清晰、同相轴连续性好。此项技术在今后的地震勘探中有指导作用和应用价值。
D brick wall geometry is a special geometry as comparison with conventional swath geometry It has the feature of which distributions of offset and azimuth are more reasonable. This geometry has not yet been applied and generated at home while wide application has been conducted abroad. The paper analyzed feature of 3 D brick wall geometry in detail and summed up in combination with real application in 3 D work area of Caracoles, Venezuela. The real data showed a high signal to noise (S/N) ratio, clearing image and good event continuity. This survey technology has guided role and applicable value in future seismic exploration.
