The application of integrated seismic reservoir prediction in forcasting hidden gas reservoir of upper palaeozoic group,north Ordos basin

The clastic reservoir in upper Palaeozoic group of North Ordos basin is hidden reservoir with lower porosity,lower permeability and thinner beds.How to foecast the distribution of river beds and the property of hydrocarbon saturation has become the crux in the exploration and development of the area.In recent years, the integrated reservoir foecasting technology based on 3-D seismic data has been applied in this area.With the application of reservoir petrophysics analysis,seismic attribute optimization,stochastic seismic inversion,seismic attenuation analysis,seicmic spectrum analysis,forward seismic modeling,seismic facies analysis,a set of valid technology has been developed in corresponding works.The application of valid seismic reservoir prediction updates the precision of reservoir description,boosts the successful probability.
