Seismic Processes for Deep Series of Strata in Biyang Depression
-
摘要: 通过对泌阳凹陷深层系地震剖面特征及该区采集、处理情况分析,提出采用叠前压制面波、多次波的新方法,充分应用炮点重新定位、地表一致性振幅补偿、面元扩展等新技术,对该区三维原始资料进行连片再处理后,提高了深层资料信噪比。Abstract: Based on analysis of seismic section features and seismic acquisition and processing in deep series of strata in Biyang depression, new technologies such as pre-stack surface wave and multiple suppression, shot point re-fix,surface consistent amplitude compensation and bin expansion are applied to re- process the initial 3-D seismic data in this area. The signal/noise ratio of data of deep strata are improved.
