For the purpose of studying reflected waves wavefield characteristics from bed collector of real gas-and-oil field situated on the north-east of West Siberian platform, lithopetrophysical simulator was done and compressional seismic wave field was calculated using finite-difference method. Synthetic wavefield from flat bed confined in thin-layer plane-parallel structure is characterized by absence of wedge-shaped pat-terns of seismic record and high correlation dependence of reflected waves amplitudes from pinching bed thickness. Lithology, porosity and nature of bed fluid saturation also causes regular changes of reflected wave amplitudes.
