Scrap beach identification method based on reflection configuration

The invention discloses a scrap-generating beach identification method based on a reflection configuration, and the method comprises the steps: S1, determining a scrap-generating beach development favorable facies belt through employing a seismic facies and a seismic attribute capable of representing the deposition of a scrap-generating beach in combination with a regional deposition background; s2, through well drilling-earthquake calibration, a scrap beach development period is divided, different-period secondary scrap beach earthquake response characteristics and influence factors are implemented in combination with a forward modeling result, and a scrap beach identification mode is established; s3, establishing a high-frequency sequence stratigraphic framework of the scrap beach through a full-three-dimensional automatic scanning interpretation technology, and determining different-period secondary scrap beach reflection structures and superposition characteristics; s4, isochronous stratigraphic slice ana
