塔河1号油田高分辨率地震勘探采集试验

Acquisition experiments for high resolution seismic survey in Tahe No.1 oilfield.

高分辨率地震勘探技术是进行地震详查时确定小幅度构造、小断层的有效手段 ,被列为圈定储层边界和进行储层描述的一种重要技术。高分辨率资料采集质量的好坏直接影响其后续处理质量及应用效果。影响高分辨率资料采集质量的因素很多 ,它们产生的影响也各不相同。本文通过对在塔河 1号油气田进行的高分辨率地震勘探采集工作分析的基础上 ,从仪器的选择、激发和接收因素的合理确定等几方面论述了采集因素对高分辨率勘探效果的影响。

High resolution seismic survey is considered as an important technology in delineation of reservoir boundaries and reservoir characterization because it can effectively indicate low amplitude structures and minor faults. The quality of seismic data acquisition directly affects the quality of subsequent processing and applications. There are many factors affecting the quality of seismic data acquisition and the effects of each factor are varied. Based on a careful analysis of high resolution seismic acquisition performed in Tahe No.1 oilfield, this paper discusses the aspects of affecting high resolution seismic survey such as instruments, exciting and receiving, etc.
