Abstract Single lithology or property parameters can not satisfy the need of complicated oil and gas reservoirs. Based on a study of statistics of logging rock physics parameters, the authors found several sensitive parameters which are linked intimately with oil and gas characteristics. Based on pre-stack seismic elastic parameters inversion results, the authors explored the fluid detection method by a borehole-seismic comprehensive technique. Practices show that the results obtained by the authors obviously improve the multi-solution problem of post-stacked inversion, and can achieve good applied effect in the oilfield.
