摘要
本文针对A油田复杂断层分布特征,以高分辨率地震资料为基础,利用谱分解技术,深入讨论了谱分解技术中调谐体和共频体解释技术对小断层精细描述的能力。实际应用表明:由谱分解技术获得的地震数据调谐体可用于分析目的层段的断层平面特征;获得的地震数据共频体可用于研究断层的剖面组合特征;联合应用调谐体和共频体可提高地震资料识别小断层的能力。
With respect to the complicated fault distribution characteristics for A oilfield,the tuning cube and common frequency data interpretation technique in spectrum decomposition technology was discussed in detail in this paper based on high resolution seismic data and by utilization of spectrum decomposition technology.The field applications show that the tuning cube acquired by using the spectrum decomposition technology could be used to analyze the fault plane characteristics of the target layer,the acquired common frequency data could be used to study the profile combination characteristics of the fault,the joint application of tuning cube and common frequency data could raise the ability of seismic data in identifying the small faults.
