Abstract：Seismic fluid discrimination describes the distribution of oil and gas reservoirs underground with seismic data, which is one of the important goals in oil and gas exploration. Pre-stack seismic inversion plays an important role in oil and gas reservoir discrimination and evaluation. Based on the review of development of pre-stack seismic inversion methods, we stress in this paper the necessity of the construction of reservoir or fluid sensitive parameters, and review some methods of fluid sensitive parameters construction and evaluation. Furthermore, we discuss the fluid discrimination methods based on model-driven and data-driven strategy respectively. Finally, theory and real data tests demonstrate that we should combine the rock physics, fluid sensitive parameters evaluation and seismic inversion technology together to ensure that the fluid type can be discriminated effectively.
