Abstract

Imaging condition is the key to realizing accurate imaging of seismic wave field,and optimizing reverse-time imaging condition is especially important in improving the application of reverse-time migration method.For this reason,based on the impulse response of zero offset and non-zero offset,this paper compares the reverse-time imaging condition based on one-way wave separation with conventional reverse-time imaging condition in detail.On the basis of the complex theory model and the real 3D seismic data of SZ working area,the imaging effects of two kinds of reverse-time imaging conditions are compared.The results show that the imaging results of the reverse-time imaging condition based on one-way wave separation can effectively attenuate the low wave number background noise,restore the effective seismic imaging information concealed under this background noise,and the stratigraphic details are characterized more clearly.These results can provide guidance for the high precision seismic imaging of complex wave fields and complex structures.

Key words： reverse-time migration imaging condition impulse response model study seismic data low wave number noise
