目前识别水合物的主要依据是BSR和其上具有高速特征的空白带。
Bottom simulating reflector ( BSR ) and amplitude blanking zone with high velocity above BSR are the indicators of hydrate .

It is difficult to recognize hydrate when BSR isn 't in existence or amplitude blanking is not obvious because of high hydrate concentration .
