英文摘要	amplitude versus offset (avo) analysis is a conventional seismic exploration technique in geophysical and lithological interpretation and has been widely used in onshore and offshore exploration. its use in marine gas hydrate research, however, is still in initial stages. in this study, avo analysis is applied to seismic profiles at drilling sites where hydrate samples have been recovered. the avo responses of free gas, bottom simulating reflector (bsrs), and gas hydrates are discussed, and the avo attributes in relation to gas hydrates are summarized. the results show that changes in intercept, gradient, fluid factor and poisson's ratio clearly reflect: (i) location of free gas and the bsr, and (ii) spatial relations between blank zone, bsr, gas hydrate, and free gas.
