摘要

针对天山南部地区复杂地表条件下的三维地震资料采集,采用了多种类型震源激发、优选激发点位、逐点设计井深、动态观测系统施工和利用卫星遥感数据进行辅助设计等有效手段;对于多类型地表以及山前巨厚砾石沉积区域,开展了综合多种方法的精细表层调查;针对静校正问题,采用了地表模型静校正和初至波静校正相结合的静校正技术,提高了静校正的精度。从实际采集结果看,资料品质与以前的二维资料相比有很大提高。
Because of the complexity of near surface conditions in south Tianshan mountain, several measures, such as shooting with various seismic sources, optimization of shooting position, variable hole depth, variable layout, satellite-remote-sensing-data aided design, were adopted in seismic data acquisition. Taking the variable near-surface conditions and gigantic gravel interval in piedmont zone into account, fine near-surface investigation was conducted. To improve statics, a combination of surface model statics and first-break statics was used. The quality of the acquired data has improved greatly compared with the existing 2D seismic data acquired in the same area.
