可燃冰试采成功 对中国能源安全意味着什么?

2017-05-19 10:19:35   新华视点

原标题:可燃冰试采成功,对中国能源安全保障意味着什么?

可上九天揽月,可下五洋采“冰”——5月18日,我国南海神狐海域天然气水合物(又称“可燃冰”)试采实现连续187个小时的稳定产气。这是我国首次实现海域可燃冰试采成功,是“中国理论”“中国技术”“中国装备”所凝结而成的突出成就。中国人民又攀登上了世界科技的新高峰,将对能源生产和消费革命产生深远影响。

看“神狐火炬”:点亮新能源时代曙光

提起能源,人们想到的往往是煤、油、气点燃的火炬而不会是冷冷的冰块,但中国科技工作者已经可以将蕴藏在海底的“冰块”点燃成熊熊燃烧的火焰,让“冰火交融”从梦想变成现实。

从5月10日起,源源不断的天然气从1200多米的深海底之下200多米的底层中开采上来,点燃了全球最大海上钻探平台“蓝鲸一号”的喷火装置。这是我国首次、也是全球首次对资源量占比90%以上、开发难度最大的泥质粉砂型储层可燃冰成功实现试采。

和人们熟悉的海底石油、海底天然气田相比,可燃冰要神秘得多。但这种由水和天然气在高压、低温情况下形成的类冰状结晶物质,却是标准的“高潜力”能源。

它燃烧值高——1立方米的可燃冰分解后可释放出约0.8立方米的水和164立方米的天然气,燃烧产生的能量明显高于煤炭、石油,燃烧污染却又比煤、石油小,更加清洁环保。

它资源储量丰富——可燃冰广泛分布于全球大洋海域,以及陆地冻土层和极地下面。估算其资源量相当于全球已探明传统化石燃料碳总量的两倍。

“可燃冰被各国视为未来石油、天然气的战略性替代能源,是世界瞩目的战略资源,对我国能源安全及经济发展也有着重要意义。”试采现场指挥部总指挥、广州海洋地质调查局局长叶建良说。

巍然矗立在蔚蓝海面中的“蓝鲸一号”,是个净重超过43000吨、37层楼高的庞然大物,今年2月刚刚“诞生”,就从烟台起航驶抵南海,投入了这项试采任务。

南海海域是我国可燃冰最主要的分布区,全国可燃冰资源储存量约相当于1000亿吨油当量,其中有近800亿吨在南海。
