关于用叠偏剖面作构造图的讨论

DISCUSSION ON CONSTRUCTING MAPS WITH STACKED AND MIGRATED SECTIONS

辽河油田物探研究所

应用叠偏剖面直接编制构造图的研究虽然已取得很大进展,但其中三维空间归位和交点闭合问题还没有真正解决。本文主要讨论并推导出求取测线与倾斜界面倾向线在地面投影线夹角α的公式,为问题的解决开辟了途径。

Though great progress has been made in constructing maps directlywith the stacked and migrated sectinns, but the problems of 3-D spatial migration and cross-point closure are not resolved yet. The stress of this paper is to derive the formula of included angle a, which is the angle included between the seismic profile and the projection of the dip line of the inclined interface on earth. Such a formula opens the path to the solution of the problems mentioned above.
