Abstract：Closer to real seismic wave propagation path by introducing ray parameter, the ray wave impedance inversion becomes a new method for reservoir prediction. Using ray wave impedance inversion we predict thin sand-shale interbeds in YA area, Subei Basin. Thin interbed reservoirs can be effectively identified by crossplot analysis of ray wave impedance with acoustic impedance from a well. And reservoir quality can be estimated by crossplots of reservoir physical parameter with ray wave impedance and acoustic impedance. Using ray wave impedance inversion, we have accurately identified two main sources of Dainan Formation, and characterized favorable sandstone distribution and sandstone updip pinchout trap.
