摘要

天然气水合物是由水和气体组成的结晶固体。气体分子,如甲烷,被困在由氢键水分子组成的空腔中。自20世纪30年代以来,天然气水合物一直是天然气行业关注的主题,因为它们是导致流动保证失效的原因。相反,自20世纪60年代以来,在北极发现的甲烷水合物,连同深水环境,既提供了确定过去和未来气候变化的手段,也提供了一种潜在的能源资源,因为地球上的大部分化石燃料被认为储存在水合物中。目前估计全球自然界中水合物结合的甲烷至少有3000万亿立方米(1.5×103亿吨碳)3)。海洋环境中存在着大量的甲烷水合物。直到20世纪90年代末,人们还认为海洋天然气水合物主要存在于低渗透率、松散的泥浆中;1994年,在日本南开海槽的砂储层中发现了大量的甲烷水合物。在高饱和度的砂岩储层中聚集的甲烷水合物似乎是一种很有前途的能源资源,因为它具有较大的渗透率,可以通过石油和天然气工业系统进行水合物分解和产气。随着这一发现,海相砂中的甲烷水合物作为一种可替代的天然气资源受到了广泛的关注。最近的研究表明,全球砂岩储层中天然气水合物的存量约为300万亿立方米(1.5×102亿吨碳)。迄今为止,日本和中国分别在南开海槽东部和中国南海进行了海上甲烷水合物生产试验。2013年世界首次海上生产测试和2017年第二次生产测试均在南开海槽东部进行,证实了积聚在砂(细)中的海洋甲烷水合物连续产气。

Methane Hydrate in Marine Sands: Its Reservoir Properties, Gas Production Behaviors, and Enhanced Recovery Methods
Natural gas hydrates are crystalline solids composed of water and gas1). Gas molecules, such as methane, are trapped in cavities composed of hydrogen-bonded water molecules. Natural gas hydrates have been a subject of concern for the natural gas industry from 1930s due to their role as a cause of flow assurance failure. Conversely, from 1960s onward, methane hydrate discovered in the Arctic, together with deep water environments, has offered both a means of determining past and future climate change and a potential energy resource, since a large fraction of the Earth’s fossil fuels is considered to be stored in hydrates2). Present estimates of global hydrate-bound methane in nature are on the scale of at least 3000 trillion m3 (1.5×103 Gt of carbon)3). Large volumes of methane hydrate exist in oceanic environment. Until the late 1990s, oceanic gas hydrates were thought to exist primarily in low permeability, unconsolidated muds; however, extensive methane hydrate deposits were discovered in sand reservoirs at the Nankai Trough off the coast of Japan in 19994). Methane hydrate accumulating in sand reservoirs at high saturation appears to be a promising energy resource because its greater permeability enables hydrate dissociation and gas production by using systems of the oil and gas industry3). Following this discovery, methane hydrates in marine sands have received widespread attention as an alternative natural gas resource. Recent studies have indicated that the amount of gas-in-place in global gas hydrates in sand reservoirs is in the order of 300 trillion m3 (1.5×102 Gt of carbon)3). To date, Japan and China have performed offshore methane hydrate production tests in the eastern Nankai Trough and South China Sea, respectively. The world’s first offshore production test in 2013 and the second production test in 2017, both at the eastern Nankai Trough, confirmed continuous gas production from oceanic methane hydrate accumulated in a sand (fine [Review Paper]
