中浅层高分辨率二维地震技术在惠州地区的应用

Application of Shallow-middle layer High Resolution 2D Seismic Technology in Huizhou Area

针对惠州地区中新统珠江组地层岩性圈闭勘探面临的三维地震分辨率较低的问题,在该地区进行了中浅层高分辨率二维地震采集试验,采用了短电缆、小容量气枪,枪、缆小埋深以及提高采样率的采集技术,通过高保真的处理手段,在中浅层获得了较为可靠的高分辨率地震资料,分辨出常规三维地震所不能分辨出来的薄层砂体,并且大大降低了采集成本,取得了良好效果。

In view of the problem of lower resolution of 3D seismic exploration of Miocene stratigraphic and lithologic traps in Zhujiang Formation,a test of shallow-middle high resolution 2D seismic data acquisition was made in Huizhou Area.By using short cable,small volume air gun,shallow buried depth of guns and cable and higher sampling rate,the acquisition technology can improve the seismic resolution.Reliable high resolution 2D seismic data are acquired by the method of high fidelity processing,which can distinguish thin sandstone that the conventional method can not,it greatly reduces acquisition costs and achieves good geologic benefits.
