摘　　要：不同地区的表层结构往往有其特殊的复杂性,由此产生的静校正问题是困扰野外采集和资料处理的关键技术难题,甚至成为制约资料品质提高的瓶颈。研究工区内,由于广泛分布冲沟、悬崖等特殊地表,使得资料处理面临的一个主要难题就是静校正问题。根据该区的资料特点和表层结构特点,提出了炮检域迭代直接静校正方法,通过共炮点叠加剖面和共接收点叠加剖面直接求取高程静校正的修正量,成功地解决了该区存在的复杂静校正问题。The near-surface structure in different areas often has its special complexity.The issue of statics arising therefrom is a key technical difficulty affecting the data processing,or even becomes the bottleneck restraining the data quality.Elevation statics specified by the client fails in the areas with gullies due to the rapid lateral variations of weathering zone.Direct statics iterated in shot and receiver domains,a new method beyond traditional technical idea of statics,is proposed and applied in the study area.Compared to elevation statics,the proposed method can better solve the issue of mid-high frequency statics.The quality of seismic sections has been greatly improved and met the need of subsequent data processing.
