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。
Gas hydrate is a clear, ice-like crystal of natural gas and water formed under specific conditions. The discovery of gas hydrates provides a vast field and a new way of thinking to find a clean and efficient new energy source instead of the increasingly depleted traditional energy source. China’s gas hydrate has a vast exploration field and a good prospect of exploration. This article reviews the research status of gas hydrate. Based on the previous researches on gas hydrates, the identification marks of gas hydrate including earthquake, geophysical logging, sedimentary rocks, geochemistry and topography are summarized. Hope to accelerate the exploration of natural gas hydrate to provide some useful clues.
