METHOD OF CONSTRUCTING CONTINUOUS SEISMOSTRATIGRAPHIC MODELS OF SECTIONS/CUBES Russian patent published in 2014 - IPC G01V1/28 

FIELD: physics.

SUBSTANCE: pairwise continuous juxtaposition of a plurality of paths of a seismic section or cube is performed. A two-dimensional function of mutual difference of fragments of seismic records of paths is calculated for each pair of seismic section paths or each pair of paths of all in-lines and all cross-lines. Values of said function are calculated for all possible combinations of the time (depth) of said pair of paths, which may belong to one seismostratigraphic level. Functions of optimum conformity of time/depth from the i-th to the k-th seismic path $$t_{i+k}={\phi }_{+}^k(t_i)$$ and $$t_i={\phi }_{-}^k(t_{i+k})$$ are calculated, followed by calculation of transfer functions for the time or depth domain of all neighbouring seismic paths. Said transfer functions enable to form a single continuous seismostratigraphic model, which is two-dimensional for the section and three-dimensional for the cube.

EFFECT: high accuracy of data for mapping formations and reconstructing parameters of a geologic environment.
