Summary:The invention belongs to the technical field of uranium mine exploration and particularly relates to a method for predicting an ancient valley uranium reservoir by using old seismic data. At present,the main prospecting means and method are drilling, but investment cost is high, the period is long, and a traditional method is difficult to predict the ancient valley uranium reservoir. The method mainly comprises steps of step 1, determining uranium reservoir attributes by utilizing known uranium mine geological drilling data through a construction criterion, a uranium source criterion, a lithology-lithofacies criterion and a rock geochemistry criterion; 2, combining a petroleum two-dimensional seismic section, carrying out fidelity amplitude preservation processing of anterior seismic data, highlighting the shallow seismic reflection information, analyzing an ancient valley seismic facies of a seismic section passing through a known uranium mine hole, carrying out wave impedance inversion according to known we
