Abstract: The study purpose of surface structure is to develop corresponding depth-velocity model of surface structure, based on the variation of velocity and depth of surface and near surface uncemented sediments in seismic survey area, and using the static correction data from each observation point to delete the interference (moveout statics) of the variation on adjacent channel. Although data acquired by nonseismic technology can not directly be used to develop such a model, but can used to describe the variation of surface or near surface geologic body, followed by developing the velocity-depth model using data from seismic micro log and refraction. This method for developing the velocity-depth model of surface and near surface according to the geological model is of uniqueness for getting static correction quantity.
