利用自激自收地震反射波原理在均匀介质条件下推导出地下反射点位置与射线路径、目的层视倾角、地震测线夹角及目的层埋深之间的复杂关系，并推广到层状介质条件下，计算反射点位置的偏移量及反射点到地面的垂直深度。用垂直深度作图，主测线联络测线可同时利用，精度高，形态逼真，断裂系统联接合理。此方法解决了目前二维叠加偏移剖面作图中存在的不闭合及数据为法线深度等问题。 The complex relationship between the position of underground reflection point and the ray path, the apparent dip of the target layer, the angle of seismic line survey and the buried depth of the target layer is derived from the principle of self-excited and self-supporting seismic reflection wave and is extended to the layered Under media conditions, calculate the offset of the reflection point position and the vertical depth of the reflection point to the ground. With the vertical depth of mapping, the main line survey line can be used at the same time, high precision, realistic shape, fracture system connection is reasonable. This method solves the problems of the current two-dimensional superimposed offset profile mapping does not close and the data is normal depth and so on.
