Near-bottom sediment cores containing gas hydrates were retrieved offshore Sakhalin, Okhotsk Sea and at Lake Baikal. Core analyses were conducted by gas, water and particle measurements to understand the formation and renewability characteristics of gas hydrates. Results obtained reveal (1) characteristics of gas hydrates depending on gas seep activities, (2) fluid seepage types with and without water, (3) carbonate formations due to chemical reactions between seeping gas and sea/lake water and (4) higher renewability potential offshore Sakhalin.

在库页岛近海、鄂霍次克海和贝加尔湖回收了含有天然气水合物的近底沉积物岩心。通过气、水和颗粒测量对岩心进行分析，了解天然气水合物的形成和可再生特征。研究结果揭示了：(1)天然气水合物的特征取决于天然气渗流活动；(2)有水和无水的流体渗流类型；(3)由天然气与海水/湖水化学反应形成的碳酸盐岩地层；(4)库页岛近海具有较高的可再生潜力。
