2013年12月17日,国土资源部在北京举行新闻发布会,宣布中国海洋地质科技人员在广东沿海珠江口盆地东部海域首次钻获高纯度天然气水合物(又称“可燃冰”)样品,并通过钻探获得了可观的控制储量。此次钻获的天然气水合物赋存于水深600~1 100 m的海底以下220 m以内的两个矿层中,上层厚15 m,下层厚30 m,自然产状呈层状、块状、结核状、脉状等多种类型,肉眼可辨。岩心中天然气水合物含矿率平均为45%~55%,其中天然气水合物样品中甲烷含量最高达99%。通过钻探23口探井,控制天然气水合物分布面积55 km2,
On December 17, 2013, the Ministry of Land and Resources held a press conference in Beijing to announce the first time that Chinese marine geoscientists and technologists have drilled samples of high-purity natural gas hydrate (also known as “combustible ice”) in the eastern waters of the Pearl River Mouth Basin in Guangdong Province. , And obtained considerable control reserves through drilling. The gas hydrate captured in this time is found in two ore layers within 220 m below the seafloor with a depth of 600 to 1 100 m. The upper layer is 15 m thick and the lower layer is 30 m thick. Naturally occurring layers are layered, massive, Like, veins and other types, the naked eye can be identified. The average rate of gas hydrate mineralization in cores is 45% -55%, of which the methane content in gas hydrate samples is up to 99%. By drilling 23 exploration wells, controlling the distribution area of gas hydrate 55 km2,
