ABSTRACT: Multi-stages volcanic are
available in HX area, shielding the seismic waves. Previous seismic
acquisitions of large size bin, less fold coverage and narrow azimuth result in
indistinct fault images, low S/N ratio and the difficulty of multi-stages
volcanic characterization. In reference to the successful experience of
domestic and overseas volcanic exploration, the low frequency excitation and
receiving, and survey with wide range, high coverage, wide azimuth should be
paid more attention, associated with two-dimensional and three-dimensional wave
equation forward modeling and real data processing contrast analysis method.
The image of underlying strata and fault are remarkably improved in the new
method, according to the processing results of new seismic data. The new method
will provide technical reference for the similar volcanic development area in
the future seismic acquisition design.
