摘要

从常规地震原始数据切除区获取被动地震数据,对通常认为是噪音的被动地震信息加以分析和处理,研究被动地震信息频率域叠加剖面和分频段能量曲线的异常特征,发现被动地震信息在频率域的能量异常与地下油气藏存在一定联系。在柴达木盆地三湖地区的实际应用表明,被动地震频率域能量异常范围与产气井位置一致,因此,利用被动地震频率域能量异常分析作为识别油气藏的补充手段,并在常规地震资料处理和反演过程中重点关注异常区域,可以提高油气勘探的效率和成功率。
Based on passive seismic data extracted from a seismic removal zone, the paper studied a processing method of seismic stacking in frequency domain, then proposed an anomaly energy analysis technique by sub-frequency band energy curve, and found a relationship between the passive seismic signal and reservoir by applications in Sahnhu area of Qaidam Basin. So the anomaly energy analysis in frequency domain for the passive seismic data can be used as an important supplementary mean for reservoir prediction, and can cause attention to the preliminary favorable zone with great benefit to seismic data processing and interpretation.
