玛9三维地震是针对地质目标要求设计部署的。针对该地区地震资料静校正问题突出、各种干扰波发育、中深层反射信号能量弱等特点,在大量原始资料分析、试验基础之上,进行了精细的高分辨率资料处理方法应用研究。整个高分辨处理重点围绕着静校正、噪声衰减、反褶积、精细速度分析与动校正、叠加偏移成像等方面展开。通过对数据的精细分析和处理,资料的信噪比、分辨率、主频都得到了提高,取得了满意的效果。
Ma 9 3D seismic designed for the geological objectives of the design and deployment. Aiming at the prominent problems of static correction of seismic data in the area, the development of various kinds of interfering waves and the weak energy of mid-deep reflection signals, the application research of fine high-resolution data processing methods is carried out based on a large amount of original data analysis and experiment. The entire high-resolution processing focuses on static correction, noise attenuation, deconvolution, fine velocity analysis and dynamic correction, superimposed migration imaging and so on. Through the careful analysis and processing of the data, the signal-to-noise ratio, resolution and frequency of the data have been improved and satisfactory results have been achieved.
