An offshore seismic data lateral reflection suppression method, comprising: calculating geographical coordinates of an offshore seismic lateral reflection source according to a diffraction theory; simulating an offshore seismic lateral reflection wave field at the geographical coordinates based on data of an actual seismic channel set; and using a matching and subtraction method to subtract the offshore seismic lateral reflection wave field from the actual seismic channel set so as to suppress the offshore seismic lateral reflection wave field in actual seismic records. The method effectively suppresses lateral reflection noise, advantageously protects and enhances an effective wave field, and increases a signal-to-noise ratio, thus improving the accuracy of imaging and geological interpretation and having good economic adaptability, and moreover saving a large amount of human and material resources and improving the efficiency of processing offshore seismic data. |
