摘要
为提高地下地质体的成像精度,需要对目标进行准确成像。多聚焦成像技术将属于不同CMP道集的接收道在同一菲涅尔带半径内进行叠加,增加覆盖次数,提高地震资料的信噪比和分辨率。根据多聚焦成像技术原理、实现过程,提出基于多聚焦成像技术的复杂构造地震成像方法,并与常规NMO动校正方法进行比较。松辽盆地滨北地区二维地震处理应用取得较好的成像效果,为研究石炭系-二叠系构造演化特征提供基础资料。
In order to improve the imaging accuracy of geological bodies,accurate imaging of the target is required.Multi-focus imaging technology stacks the receiving traces belonging to different CMP gathers within the same Fresnel Zone radius,increasing folds and improving the signal to noise ratio and resolution of seismic data.According to the principle and implementation process of multi-focus imaging technology,a complex structure seismic imaging method based on multi-focus imaging technology is proposed and compared with the conventional NMO dynamic correction method.The application results of2 Dseismic processing in Binbei Area of Songliao Basin show that good imaging results is achieved.The results provide a good data foundation for the in-depth study of tectonic evolution characteristics of the Carboniferous-Permian Formation.
