中国石化新闻网讯据普氏能源资讯4月10日东京报道,日本经济产业省的一名高级官员周一在东京表示,由于第二次海上生产试验将决定未来的商业生产,日本将对来自甲烷水合物的天然气进行将是“至关重要的”海上生产试验。
日本经济产业省油气部门主管Yuki Sadamitsu在一次新闻发布会上说,《地球号》钻井船已抵达爱知县渥美半岛以南80公里的Nankai深海槽的Daini-Atsumi圆丘并将完成已在这个位置上开钻的两口生产井。
这名主管说,第二次海上甲烷水合物生产试验将标志着朝甲烷水合物商业生产迈出至关重要的一步。
这名主管补充说,一旦生产井在水深1000米海上再钻进50至60米抵达海床以下大约300米的甲烷水合物,《地球号》钻井船将使用降压系统开始从甲烷水合物中开采天然气。
2013年3月,日本在为期6天的首次海上生产试验中从甲烷水合物中平均每天生产了2万立方米天然气。这次试验将是日本在全球进行的第二次海上甲烷水合物生产试验。日本在10多年前就着手实地调查研究和测试各种技术。(李 峻 编译)

Japan says methane hydrate output test crucial for commercial production
Japan is set to conduct what will be a "crucial" offshore output test of gas from methane hydrate as its results will decide the future of commercial production, a senior official at the Ministry of Economy, Trade and Industry said Monday.
Chikyu driing ship arrived at the Daini-Atsumi Knoll in Nankai trough, 80 kilometers (49.6 miles) south of the Atsumi Peninsula in Aichi prefecture and will start finishing the two production wells already drilled at the site, Yuki Sadamitsu, METI's director of oil and gas division, said at a press briefing.
The test would mark a crucial step in the path to commercialization of methane hydrate production, Sadamitsu said.
Once the production wells are drilled another 50-60 meters to reach methane hydrate layers about 300 meters below the seabed at a water depth of around 1,000 meters, the Chikyu will start extracting gas from methane hydrate using the decreased pressure system, he added.
This will be the second offshore methane hydrate production test globally after Japan produced 120,000 cubic meters, or 20,000 cu m/day, of gas from methane hydrate in a six-day offshore production test at the Daini-Atsumi Knoll in March 2013. This followed more than a decade of field research as well as testing of various technologies.
