%X The basic principles and calculation steps of model-constrained 3-D refraction static correction were introduced, the technology of 3-D pumping line, destination layer quality control, 3-D velocity interpolation, 3-D bottom interpolation were provided, and a specific examples in a work area of the western region was illustrated in this paper. The results show that the method of the near-surface depth - time velocity model using the micro-logging, small refraction, delay time of every points uing first break travelling time of shot record, by which inversing layer thickness of the bottom and elevation, computing eventual static correction, can significantly increase the inversion precision of low-velocity layer, and better solve the static correction problem of complex structure of surface.
