摘要
在地表高差变化大的地区，地震资料处理已较普遍地采用以浮动基准面为参考面的处理方法。如何对这种资料进行解释成图，文中提出了两种归位到水平基准上的校正方法，并给出了校正公式。为消除填充速度的影响，提出建立高精度平均速度场的方法。指出解释成果时，要注意是针对何种参考面，否则由于构造形态有较大差别，而给钻探工作造成陷阱。
Processing methods that take floating datum as reference datum have been commnly applied to seismic data processing in areas with large surface altitude difference. Two correction methods regressing to horizontal reference daturn and the correction formulas are given in this paper to process and map these data. In order to eliminate the influence of packing speed, a method to establish average velocity field of high accuracy is presented. It is pointed out that attention should be given to the types of reference datum in interpretation, otherwise ralative large difference of structure feature can create pitfalls in exploratory drilling.
