1前言1971年，Stoll等人观察到海相沉积样品在巨大围压下渗出甲烷井产生了试管中的气体水合物。当年有关文献记载：“样品停止昌泡后，样品围压降至常压，压力釜移去顶盖，盖底覆有一层雪状结晶物，这种结晶物在常温下保存15分钟后溶化并放出气体（Stoll等，1971）”。该重大发 1 Introduction In 1971, Stoll et al. Observed that a sample of marine sediment oozing out of a methane well under large confining pressure produced gas hydrates in the test tube. Year literature records: “After the sample was stopped Chang bubble, the sample pressure down to atmospheric pressure, the autoclave removed the top cover, the bottom covered with a layer of snow-like crystals, this crystal was stored at room temperature for 15 minutes after the dissolution and Gas release (Stoll et al., 1971) ”.
