摘要: 针对南黄海盆地碳酸盐岩沉积层对地震波场产生很强的散射和屏蔽作用、深层反射能量弱等特殊地震地质条件,开展大量的四子阵立体阵列组合模型设计,并优选出性能较优的阵列组合,使用优选出的四子阵列组合震源进行野外地震采集试验,获得了较好的中生界深层地震反射,取得了较好的应用效果。

Abstract: The occurrence of carbonate strata in the South Yellow Sea Basin may block seismic waves to penetrate into the deeper part. Based on numerical modeling, we develop a three-dimensional seismic source by experiment of different combination of 4 groups of air gun arrays. The 4 sub-arrays three-dimensional seismic source has already been tested in the field. The result was rather encouraging. By using this new seismic source, it may improve imaging effect of the Mesozoic in this region;
