从地质学方面探讨了东海陆坡天然气水合物的成矿条件,认为该区具有良好的成矿环境;通过穿越东海陆坡区的数十条多道地震及高分辨率地震剖面资料的判读,确定出天然气水合物的分布区,并估算了天然气的储量,预测了在该区域寻找天然气水合物矿藏的远景。

This article discuss conditions of the mineralization of gas hydrate from geology,believes that this area has a good condition of mineralization of gas hydrate in the continental slope of the East China Sea. By distinguishing the data of multichannel seismic reflection profile and high resolution seismic profile of several ten lines in the continental slope areas,we have divided where the gas hydrate resources exist,and estimated the amount of reserve of gas in the places. All these provide a good opportunity of seeking mineral resources of gas hydrate in the area and calculating prospect of gas hydrate resources in the future.
