The experience of the construction of the structural framework of the geological
model in conditions of unconcordant productive strata bedding is
considered. Ways of construction of structural and parametric model framework
are analyzed. The method of restoring the stratigraphic thicknesses in
the area of the strata roof washout and in the absence of the lower stratigraphic
boundary, untapped by drilling, that allows the correct partition of

thin-layer section interlayers, is constructed.
