陆基孟,王铁男:用 DMO 和 PSI 方法处理二维物理模型数据的结果,《石油地球物理勘探》,23(1)1988:1～20为了更好地对文献[1]提出的 DMO(Dip moveout,倾角时差校正)和PSI(Pre-stack imaging,叠前成像)方法进行检验,并说明它的优点和效果,对文献[2]中设计和制作的二维反向断层地震物理模型所提供的数据进行了处理。本文介绍了这项处理的三个具体流程和处理的结果:①速度分析→动校正→水平叠加→偏移;②DMO→速度分析→动校正→水平叠加→偏移;③DMO→PSI→速度分析→动校正→叠加。文中还就以上结果进行了比较分析,证明这种 DMO 和 PSI 方法的正确性及其在提高地震资料质量方面的显著作用。
LU Ji-Meng, WANG Tie-Nan: Results of Two-Dimensional Physical Model Data Processing with DMO and PSI Methods, Petroleum Geophysical Prospecting, 23 (1) 1988: 1-20 In order to better understand the DMO (Dip moveout, Dip and azimuth correction, and pre-stack imaging (PSI) methods, and illustrate its advantages and effects. The data provided by the 2D reverse faulting seismic physical model designed and produced in [2] Processed. This paper presents three specific processes and results of this process: ① velocity analysis → dynamic correction → horizontal stacking → offsetting; ② DMO → velocity analysis → dynamic correction → horizontal stacking → offsetting; ③ DMO → PSI → velocity analysis → Dynamic correction → overlay. The above results are also compared and analyzed to prove the correctness of the DMO and PSI methods and their significant role in improving the seismic data quality.
