Aiming at the actual state of seismic profile being seriously affected by the superficial factors in mountainous regions, the model traces composed by stacking with multiple side-by-side CDP gatherings have been adapted. The model traces having met our needs would tend to be a steady state in the line. In this case the time position simply represents that of zero reference line of static correction. The residual static correction either inside or amidst the gatherings could be completed simultaneously, if only the traces of the CDP gatherings are pointed to each model trace correspondingly. As a result the signal-to-noiseratio in the sections is then improved, the king amplitude is increased, so as to make shallow, middle and deep reflectors smooth as well as stac continous, the shape of structures become distinct…etc., strictly speaking, it seems to be much superior as compared with the autostatic correction method conducted by imported digital computers 170-4 and 172-4.

山区表层因素严重影响地震剖面的质量,我们采用了多个相邻的CDP道集同相叠加组成模型道,当道数足够多时,模型道在整个测线上趋于稳定,它的时间位置就是静校正零基准线的位置.只要将CDP道集内各道向对应的模型道对齐,就可以同时完成道集内和道集间的剩余静校正.本方法可提高剖面的信噪比,增强叠加能量,使浅中深反射层光滑连续,构造形态清晰……,它比引进的1704和1724机的自动剩余静校正方法更加完善.本方法程序简单,占用内存量小,处理速度快,适用于小型计算机.方法的适应性广泛,无论是弯、直测线;单、多次覆盖剖面都可应用.本方法也可作为修饰性程序应用于地震勘探的数字处理中.

In view of the fact that stacking energy along a coherent event is the strongest and on the basis of the conventional wide line stack, the crossdips of reflectors and arrival time of reflections can be picked up automatically by means of the result of weighted stack of dip sweep. And then once again the "layering stack" between the dips obtained and the weighted stacking traces corresponding to their adjacent sweep dips needs to be performed.

Bao Jishan and Li Luming:Velocity analysis using 2D slant-stack approach,OGP,23(1)1988:34~54 In conventional velocity analysing,people use adjacent CDP ga- thers to make velocity spectrum,without dip moveout considered.With the increase of reflector dip,the dip moveout increases,but the stack- ing energy of adjacent CDP gathers decreases;therefore,the phenomenon of missing layer happens.In recent years,a velocity analysis method which is applicablc to slant-stack follows the seismic slant-stack techni- que.This method has two key points:(1)DMO correction is used in velocity scanning in making velocity spectrum by slant-stack approach; (2)in scanning stacking,both waveform similarity and energy criterion are used in weighted stacking.This method is not affected by reflector dip;consequently,the velocity determined by this method is more ap- proximate to true velocity in medium.The slant-stack velocity module presented in the paper can be used(1)to make velocity spectra by both slant-stack approach and horizontal-stack approach,(2)to extract quite reliable velocity information and quite accurate dip information,and (3)to perform static correction.

包吉山,李录明:二维倾斜叠加速度分析,《石油地球物理勘探》,23(1)1988:34~54在传统的速度分析方法中,是将相邻几个 CDP 道集组合在一起制作速度谱,不考虑界面倾角引起的时差。实际上这种时差是随界面倾角的增大而增大的。此外,相邻 CDP 道集的叠加能量还随倾角的增大而衰减,因此出现丢层现象。近年来,随着倾斜叠加方法的出现和发展,一种适用于倾斜叠加的速度分析方法也应运而生,此法的关键是在制作倾斜叠加速度谱时,把倾斜动校正用于速度扫描,在扫描叠加时又利用地震波的相似性和能量准则进行加权叠加。此法不受界面倾角的影响,由此法求出的速度更接近实际介质的速度。本文提供的倾斜叠加速度模块既可作倾斜叠加速度谱,又可作水平叠加速度谱,既可提取可信度较高的速度信息,又可检测精度高的倾角信息,还可顺便完成一次静校正处理。
