Abstract: 5D seismic fluid identification, that is, the use of 5D seismic data to identify and describe the
fluid characteristics of complex reservoirs, which is a frontier and important problem in the industry. Firstly,
with the rock physics mechanism, the relationship between the anisotropic reservoir parameters and physical
parameters is studied, and the anisotropic fluid factor f ani with high sensitivity parameters is constructed. The
rationality and practicability of the fluid factor are verified. Then, the anisotropic inversion algorithm is used
to mine the rich azimuthal anisotropy information in the 5D seismic data. The anisotropic fluid factor used
to characterize the subsurface fluid is obtained by inversion, and the 5D seismic fluid identification is realized.
The practical application results show that the new anisotropic fluid factor and anisotropic inversion algorithm
can obtain reservoir fluid characteristics from five-dimensional seismic data stably and reliably, and provide a
new theoretical method for 5D seismic fluid identification.
Keywords: 5D seismic fluid identification; Anisotropic factor construction; 5D seismic interpretation; Seismic
inversion
