APPLICATION OF THE CURVE-RECOMPOSITION TECHNOLOGY TO THE LATERAL PREDICTION OF RESERVOIRS

Acoustic curves are basic data essential for the wave impedance inversion based on logging restraint. But the acoustic data obtained from practical work usually cannot well reflect the changing rules of subsurface lithology. So, it is needed sometimes to refer other logging information in order to do curve recomposition. Combined with the examples of wave impedance inversion in LMZ area, a curve recomposition method was introduced in this paper, whichincluding curve sifting, data standardization, curve analyses and data recomposition these steps.
