【摘要】 模型层析法融层位控制、射线追踪、波动方程等多种理论于一体,而且射线追踪是在三维空间进行射线追踪,在计算层速度的同时求出反射点偏离入射点的空间偏移量,建立速度场及空间地质模型,并从空间上进行偏移归位。采用模型层析法,可消除地层大倾角、大幅度构造翼部产生的速度畸变,获得精细准确的构造图。更多还原

【Abstract】 Model chromatography is consisted of multi-theories of horizon control, ray track and wave equations, the ray track is to conduct it in a 3 dimensional space, calculate interval velocity and simultaneously calculate the spatial offset of reflection point deflecting incident point , establish a velocity field and spatial geologic model to carry out migration reversion. Geodetic inclination angle, large scale of velocity distortion caused by tectonic wings are eliminated , thus an accurate structural diagram is obtained.更多还原
