CALCULATION OF DIFFRACTIONS IN TWO-DIMENSIONAL LAYERED MEDIA

HUANG YAN-HU YAO YAO(China University of Geoscienccs, Wuhan)  
In this paper, calculation of diffractions i discussed. It is a part of our efforts made for solving the problems involved in two-dimensional seismic man-machine interactive interpretations by Ray-method. It is a continuation and development of paper [5]. According to the physical natures of waves, the concepts of equivalent shot-point, equivalent geophone-position and equivalent interface between meda are introduced. The applicable extent of Berryhill's formulae for the calculation of diffractions[5] is extended to the construction of oblique interfaces and wedgeouts. Thus the calculation of diffractions in two-dimensional layered media is solved. This work incorporated with the work finished in papers [1-3] makes it possible to solve the forward problem of two-dimensional seismic man-machine interactive interpretations in practice.
