本文在P·M·Shah1973年对二维情形定义的一个速度(V_NMO)并将其与地层参数联系起来的DIX型公式的基础之上,对同一个CDP点定义V_NMOX和N_NMoy两个速度,经严格的数学推导,得到了三维情形下的相应结果,我们称之为三维的DXI型公式。文章还通过理论模型的正、反演试算,证明了公式的可靠性和准确性。

Based on VNMO for 2D which was defined by P. M. Shah in 1973 and integrated the stratigraphic parameters with it, A corresponding result similar to 3 D has been reached after the mathematical derivation done with meticulousness. That's what we called "3-Dimensional Dix-Equation". Also, the reliability as well as accuracy of the equation verified by way of forward and inverse operation of theoretical model are demonstrated in the paper.
