【摘要】 GLOG（虚速度测井）处理是获取高分辨率波阻抗剖面的一种地震数据反演过程。其主要步骤包括于波处理（QCOMP、TCOMP和NMP）、合成地震记录（CVL）和地震数据反演（GLOG）。面积GLOG处理是在偏移后的三维数据体上进行的，处理中的关键问题是如何解决用少量井资料来控制整个面积数据时标定系数的时空变化问题。本文结合实例介绍了三维资料面积GLOG处理的主要技术思路和实现方案，给出了满足精度要求的处理结果。更多还原

【Abstract】 Pseudo-velocity log (GLOG) processing refers to a seismic inversion problem designcd to create high-resolution,acoustic impedance sections, prior to whieh two procedures including wavelet processings (QCOMP, TCOMP, and NMP) and synthetic scismogram (CVL ) are in demand as its preprocessings. The areal GLOG processing is performed on migrated 3D data volumes, to which the key is to deal with the temporal and spatial variation of calibration coefficients when only a small amount of well data are available to control thc cntirc areal data. This paper illustrates with real data the underlying idea and practical procedures of the areal GLOG processing-for 3D data. Some desired results are also given in this paper.更多还原
