【摘要】 天然气水合物是天然气和水在特定条件下形成的一种透明的冰状结晶体。天然气水合物的发现为寻找清洁高效的新型能源,以取代日益枯竭的传统能源提供了一个广阔的领域和新的思维方式。我国天然气水合物具有广阔的勘探领域和良好的勘探前景。本文对天然气水合物的研究现状进行了综述。在总结前人关于天然气水合物研究的基础上,总结归纳了天然气水合物的地震、地球物理测井、沉积岩石、地球化学、地形地貌等识别标志。企望对加速天然气水合物的勘探提供一些有益的线索。更多还原

【Abstract】 Gas hydrates is a kind of crystal icy substance formed by water and natural gas in special condition .The discovery of gas hydrates provided a wide sphere and a new way of thinking for searching clean and effective energy source to replace increasingly exhausted tradition energy source .Moreover in our country there are a wide realm and bright prospects for the exploration of gas hydrate. This paper has summarized the progress on the study of gas hydrates. And based on the former research about gas hydrates, the integrative identity symbol of gas hydrates was summarized in the aspects of seism, geophysical well logging, sediment and rock, geochemistry, topographty and physiognomy. In the end, the author hope it may provide an useful clue for exploration of this kind of resource.更多还原
