黄土塬梁及沟壑区三维地震勘探采集技术探讨

Discussion on three dimensional seismic exploration acquisition technology in loess plateau beam and gully area

黄土塬梁及沟壑地区,第四系纵横方向变化、潜水面变化大等不利的浅表层地震地质条件,给地震资料采集带来诸多困难。本文分析了黄土塬梁及沟壑地区地震数据采集的难点,针对这些难点,依据理论基础并结合施工经验,总结了解决该类地区数据采集问题的技术方法。

In the loess plateau beam and gully area,the unfavorable shallow seismic geological conditions such as the Quaternary change of vertical and horizontal direction and the large change of the phreatic surface bring many difficulties to the seismic data acquisition.This paper analyzed the difficulties of seismic data acquisition in the loess plateau beam and gully area.In view of these difficulties,based on the theoretical basis and combined with the construction experience,the technical methods to solve the problem of data acquisition in this area were summarized.
