摘要 地震反射波形特征对判断地层中是否存在天然气水合物及其下伏游离气层具有重要指示意义。BSR波形极性与海底反射相反,它大致代表含水合物层的底界;当地层中富含水合物及下伏游离气时,其波形特征亦有明显的反映,据此可推断水合物成矿带顶界和游离气层底界的大致位置。 It＇s very significant to use the wiggled character of seismic reflector to distinguish the gas hydrates and underlying free gases in the strata. BSR is the bottom of the gas hydrates zone, and the polarity of the wiggle of BSR and seafloor are reverse. If gas hydrates and free gases are existed in the strata, the wiggled character of BSR will be shown clearly, so that the position of the top of gas hydrates zone and the bottom of free-gas-bearing layer can be concluded approximately.
