无人机航拍视角下的蓝景一号钻井平台。
5月18日，国土资源部部长姜大明在南海神狐海域“蓝鲸一号”钻井平台宣布：
我国首次海域可燃冰（天然气水合物）试采成功！
这是一个历史性突破！中央发来贺电！
新华社北京5月18日电
中共中央、国务院对海域天然气水合物试采成功的贺电
国土资源部、中国地质调查局并参加海域天然气水合物试采任务的各参研参试单位和全体同志：
在海域天然气水合物试采成功之际，中共中央、国务院向参加这次任务的全体参研参试单位和人员，表示热烈的祝贺！
天然气水合物是资源量丰富的高效清洁能源，是未来全球能源发展的战略制高点。经过近20年不懈努力，我国取得了天然气水合物勘查开发理论、技术、工程、装备的自主创新，实现了历史性突破。这是在以习近平同志为核心的党中央领导下，落实新发展理念，实施创新驱动发展战略，发挥我国社会主义制度可以集中力量办大事的政治优势，在掌握深海进入、深海探测、深海开发等关键技术方面取得的重大成果，是中国人民勇攀世界科技高峰的又一标志性成就，对推动能源生产和消费革命具有重要而深远的影响。
海域天然气水合物试采成功只是万里长征迈出的关键一步，后续任务依然艰巨繁重。希望你们紧密团结在以习近平同志为核心的党中央周围，深入学习贯彻习近平总书记系列重要讲话精神特别是关于向地球深部进军的重要指示精神，依靠科技进步，保护海洋生态，促进天然气水合物勘查开采产业化进程，为推进绿色发展、保障国家能源安全作出新的更大贡献，为实现“两个一百年”奋斗目标、实现中华民族伟大复兴的中国梦再立新功！

这事儿为什么受到如此重视？
可燃冰，又称天然气水合物，分布于深海沉积物或陆域永久冻土中，是由天然气与水在高压低温条件下形成的类冰状结晶物质。
其燃烧后仅会生成少量的二氧化碳和水，污染比煤、石油、天然气小很多，但能量高于煤、石油、天然气十倍。
这次试采成功是我国首次、也是世界第一次成功实现资源量全球占比90%以上、开发难度最大的泥质粉砂型天然气水合物安全可控开采，为实现天然气水合物商业性开发利用提供了技术储备，积累了宝贵经验。

可燃冰储量巨大，据估计可燃冰中所含有机碳的总资源量相当于全球已知煤、石油和天然气总量的两倍，被国际公认为石油、天然气的替代能源，是世界重要的战略资源，对我国能源安全及经济发展也意义重大。
全球可燃冰研发活跃的国家主要有中国、美国、日本、加拿大、韩国和印度等，各国竞相投入巨资开展天然气水合物试采，竞争异常激烈。
美国、加拿大在陆地上进行过试采，但效果不理想。

日本于2013年在其南海海槽进行了海上试采，但因出砂等技术问题失败。2017年4月在同一海域进行第二次试采，第一口试采井累计产气3.5万立方米，5月15日再次因出砂问题中止产气。
韩国、印度、越南、菲律宾、印度尼西亚等国家也制定了可燃冰试采计划。

与日本试采的可燃冰矿相比，我国海域主要属于泥质粉砂型储层，这也是占全球90%以上比例的储藏类型。
砂细导致渗透率更差，同时我国的可燃冰水深大、储层埋层浅，施工难度更大。
我国的突破，对于全世界而言更具有可参考和借鉴的价值。

此前，吉林大学研究团队在海拔4000米的青海省木里盆地，首次钻获了我国陆地可燃冰实物样品，成功实现了陆地可燃冰试开采，填补了我国陆域可燃冰钻采技术的空白。
中国可燃冰资源储存量约相当于1000亿吨石油，其中南海海域是我国可燃冰的主要分布区，有近800亿吨储量，突破海域可燃冰钻采技术意义更为重大。
We wholehearted work so we are professional !
