摘要
西藏羌塘盆地地区在地层的演变形成过程中,由于地质条件复杂,地下碳酸盐岩目的层波阻抗差异小、界面反射信号弱。针对这些特点,探讨了本地区地震资料处理方法,分析原始记录及地质特征,认识各种干扰波的特征与地表条件的关系,并采取相应的措施对地震数据进行静校正、去噪、叠加等处理,取得了良好的效果,可为今后在此类地区进行地震资料现场处理提供借鉴。
In the process of stratigraphic formation in Qiangtang Basin region, and due to the complex geological condition, underground carbonate target layer wave impedance difference is small, and the interface reflection signal is weak. Based on these features, the regional seismic data processing method is studied, the original data and geological characteristics are described, the characteristics of various interference waves and the relationship of the surface conditions are analyzed. Besides, some measures are taken like the seismic data static correction, de-noising, stacking and other processing methods, which has achieved good results.
