Abstract
Restrictions of model of static сorrections, which is used at indemnification of a non-uniform top part of a section are considered. Three types of heterogeneity of the top part of a section are discussed: a relief of a day time surface, a weathering zone and shipped heterogeneity. The problem of indemnification of influence of these factors is considered in connection with a problem kinematic interpretation of the reflected waves. On numerical models it is shown, that the traditional model of static сorrections with the certain restrictions is suitable only for indemnification of а weathering zone. For indemnification of a relief and shipped heterogeneity a section it is necessary to use more correct ways, based on construction of aprioristic speed model of environment and numerical methods of calculation of reflection raypaths.
