巴基斯坦复杂地表区地震采集技术

Seismic acquisition technology in Pakistan complicated surface area.

针对巴基斯坦地震勘探面临地表条件复杂、地下构造复杂、安全与环境因素影响大等难点,结合BGP在类似地区的地震作业经验,BGP巴基斯坦项目经理部在实践中总结出了适合当地特色的一套完整的地震采集技术。其中包括卫星图片应用技术、混合震源激发技术、多种检波器接收技术、采集设计技术、宽线采集技术、静校正技术、现场质量控制技术,取得了良好的地震采集效果,为在类似地区的地震采集提供了借鉴。

Due to the difficulties of complicated surface conditions, complex underground structures and larger influence of security and environment factors in Pakistan seismic exploration, and in combination with experiments of seismic jobs that BGP carried out in similar areas, the BGP Pakistan Department of Management summarized a set of complete seismic acquisition technology appropriate to local characters in practice, including satellite photo application technique, hybrid source shooting technique, multiple geophones receiving technique, acquisition design technique, wide-line acquisition technique, static corrections technique and in-site QC technique, achieving good seismic acquisition effect, which provided a reference to seismic acquisition in similar area.
