天然气水合物开采试验取得重大进展天然气水合物是一种地球上尚未商业化开采的新能源,资源量十分丰富,据估算全球资源总量约为2.1×1016 m3,相当于全球已探明传统化石能源总量的2倍。目前已有30多个国家和地区开展了对天然气水合物的开发研究,2012年美国、日本等国合作在阿拉斯加北坡的水合物开采试验与2013年3月日本在其近海海域的水合物开采试验均取得成功,意味着天然气水合物的开采迈出了重要的一步。应用降压开采法和二氧化碳置换法成功进行了日本和阿拉斯加水合物的开采:降压法是利用储层与井筒之间的压力梯度驱动
Gas hydrate exploration test made significant progress Gas hydrate is a new energy source on the earth that has not yet been commercially exploited. It is estimated that the total amount of resources in the world is about 2.1 × 1016 m3, which is equivalent to the world’s proven traditional fossils 2 times the total energy. At present, more than 30 countries and regions have carried out research and development on natural gas hydrate. In 2012, the cooperation test between the United States, Japan and other countries on the northern slope of Alaska and the hydrate exploitation in Japan in March 2013 The success of all experiments means that gas hydrate mining has taken an important step forward. The Japanese and Alaskan hydrate production has been successfully exploited by depressurization and carbon dioxide displacement: the depressurization method is driven by the pressure gradient between the reservoir and the wellbore
