【摘要】 山西黄土塬地区地表地质条件复杂、低降速带不稳、黄土厚度变化较大且高程变化剧烈,导致地震记录信噪比低,静校正问题突出。通过对地震数据静校正处理,总结出了层析静校正和折射波剩余静校正的结合,能够很好地解决区内不同波长的静校正问题。这两种方法的结合,在实际的生产中较好地改善了叠加剖面同相轴的连续性,提高了勘探精度以及整体效果。更多还原

【Abstract】 In Shanxi loess tableland areas,the surface geological conditions is complex,Low deceleration zone is unstable and has a great variation in elevation,so that the signal-noise-ratio(SNR) in seismic record is low and the static correction problem is severe.This study shows it can be solve static correction problems well by combined using the tomographic static correction and refraction residual static correction with different wavelengthsbasing on summarizing the seismic data processing static correction.This solution improves the continuity of the stack section with seismic event in the actual production as well as the precision of exploration and the integral effect.更多还原
