The invention discloses a self-adaptive wave equation wave field continuation static correction method. The method uses velocity field information obtained by tomographic inversion, original single-shot seismic data is used for wave equation continuation, and continuation of the seismic data acquired at the surface onto a reference plane is carried out. Starting from a common shot gather record, a finite different method is used for continuation from the surface to a high-speed layer top interface, and then a phase shit method is used for continuation from the high-speed layer top interface onto a fixed reference plane. The data after continuation are subjected to gather extraction into common detector gather data, and then the finite different method and the phase shift method are used for wave field continuation of the common detector gather record. After the continuation of the common detector data, the data is subjected again to extraction into common shot gather data. In the process of the wave field continuation, a velocity field smoothing parameter which can be automatically adjusted based on the complexity of a velocity field is added, the velocity field after smoothing process is used for continuation, and the problem of low accuracy at a large dip angle by the finite different method can be solved.
