Reflection data in CMP has influenced seriously in static calculations，especially in some highly weathered and structurally altered circumstances． Because of static correction in the existed problems and requests， the authors studied the angle － dependent tomographic static correction，and discussed its basic theory， including the establishment of forward model，the calculation theory of tomography and tomographic static correction． The usage of theoretical models and practical information on the method has been validated． The results show that using these methods to calculate static correction in a complex area，the quality of static correction is greatly improved．
