High precision refraction static correction data inversion method

The invention relates to a geophysical prospecting method which is a high-precision refraction static correction data inversion method. The method comprises the steps: the production shot first arrival data of an earthquake work area are collected; the refraction wave delay time is calculated out through the following steps; and the data of micro logging control points and the information of refraction delay time are used for obtaining the time-depth curve of the low deceleration layer of the work area. Micro logging control points provide a target layer depth (HD), a refraction result offered delay time tD, a comprehensive tD(HD) curve and a conversion tD curve, thereby obtaining a reliable surface structure model and a high-precision low deceleration zone static correction result profile map. The invention has the advantages that the depth curve constrains and inverses the delay time when the high-precision low deceleration layer is used; the depth errors caused by the inaccurate velocity are eliminated; the application condition is wide; the adaptability is strong; and the result precision is finally improved.
