Method of deriving the fluid content and reservoir rocks from the pre-stack inversion of seismic data

摘要

(57) how to derive the fluid content and reservoir lithology target position of the (400) (110) [summary] pre-stack seismic reflection database. Target position, the method, underground rock quality target position in the (400) and by using inversion of the pre-stack seismic reflection data for both the (110) and (200) a calibration position with a fluid content and subsurface lithology known and I derive the fluid contents. Inversion process (200) is a viscoelastic inversion fully taking into account the friction effect of seismic wave propagation. A result of the inversion process is the underground elastic parameters of a set of calibration on both positions and goals. I derive the fluid content and underground lithology (399) target position in the (400) compared along with the (146) fluid content and basement lithology known in the calibration position, the relative magnitude of the underground elastic parameters of these.
