中国新闻网

中新网3月26日电 据自然资源部官方微博消息，3月26日，自然资源部召开的汇报视频会上发布，中国海域天然气水合物(即“可燃冰”)第二轮试采日前取得成功并超额完成任务。在水深1225米的南海神狐海域，试采创造了“产气总量、日均产气量”两项新的世界纪录，实现了从“探索性试采”向“试验性试采”的重大突破。
2007年6月，首次在南海神狐海域发现可燃冰，2008年，在青海祁连山首次发现陆上可燃冰。2017年5月10日，神狐海域天然气水合物试采点火成功，来自深海的冰火在湛蓝的海面上连续燃烧了60天，累计产气量超过30万立方米，平均日产5000立方米以上，甲烷含量最高达99.5%，为后续科学研究积累了大量翔实可靠的数据资料。2017年11月3日，经国务院批准，将天然气水合物列为独立矿种，至此中国已发现173种矿产。
据介绍，此次试采取得一系列重大突破。一是创造了“产气总量、日均产气量”两项世界纪录，实现了从“探索性试采”向“试验性试采”的重大跨越。本轮试采1个月产气总量86.14万立方米、日均产气量2.87万立方米，是第一轮60天产气总量的2.8倍。试采攻克了深海浅软地层水平井钻采核心关键技术，实现产气规模大幅提升，为生产性试采、商业开采奠定了坚实的技术基础。中国也成为全球首个采用水平井钻采技术试采海域天然气水合物的国家。
二是自主研发了一套实现天然气水合物勘查开采产业化的关键技术装备体系，大大提高了深海探测与开发能力。形成了六大类32项关键技术，其中6项领先优势明显。研发了12项核心装备，其中控制井口稳定的装置吸力锚打破了国外垄断。这些技术装备在海洋资源开发、涉海工程等领域具有广阔应用前景，将带动形成新的深海技术装备产业链，增强我国“深海进入、深海探测、深海开发”能力。
三是创建了独具特色的环境保护和监测体系，进一步证实了天然气水合物绿色开发的可行性。自主创新形成了环境风险防控技术体系，构建了大气、水体、海底、井下“四位一体”环境监测体系。试采过程中甲烷无泄漏，未发生地质灾害。

China's combustible ice mining sets world records for total gas production and average daily gas production
China News Network
Release time: 03-2613: 53 China News Network official account
China News Network, March 26th. According to the official Weibo news from the Ministry of Natural Resources, on March 26th, a report video conference held by the Ministry of Natural Resources was released. Achieved success a few days ago and exceeded the task. In the Shenhu area of the South China Sea with a water depth of 1,225 meters, the trial production set two new world records of "total gas production and average daily gas production", realizing the significant transition from "exploration trial production" to "experimental trial production". breakthrough.
In June 2007, combustible ice was first discovered in the Shenhu area of the South China Sea. In 2008, land-based combustible ice was first discovered in the Qilian Mountains of Qinghai. On May 10, 2017, the trial production and ignition of natural gas hydrates in the Shenhu Sea area was successfully ignited. Ice fires from the deep sea continued to burn for 60 days on the blue sea surface. The cumulative gas production exceeded 300,000 cubic meters, with an average daily output of more than 5,000 cubic meters. The content is up to 99.5%, which has accumulated a lot of informative and reliable data for subsequent scientific research. On November 3, 2017, with the approval of the State Council, natural gas hydrate was listed as an independent mineral. So far, 173 minerals have been discovered in China.
According to reports, this trial has taken a series of major breakthroughs. First, it has created two world records of "total gas production and average daily gas production", and achieved a major leap from "exploration trial production" to "experimental trial production". In this round of trial production, the total gas production for one month was 86,141,000 cubic meters, and the average daily gas production was 28,700 cubic meters, which was 2.8 times the total gas production in the first round of 60 days. The trial mining has overcome the core key technologies of horizontal well drilling and production in deep soft shallow formations, and has achieved a substantial increase in gas production scale, laying a solid technical foundation for productive trial mining and commercial mining. China has also become the first country in the world to test and extract natural gas hydrates in sea areas using horizontal well drilling technology.
The second is the independent research and development of a set of key technology and equipment to realize the industrialization of gas hydrate exploration and production system, which has greatly improved the deep sea detection and development capabilities. Thirty-two key technologies in six categories have been formed, six of which have obvious leading advantages. Developed 12 core equipment, of which the suction anchor of the device that controls the stability of the wellhead broke the foreign monopoly. These technical equipments have broad application prospects in marine resource development, maritime engineering and other fields. They will drive the formation of a new deep-sea technical equipment industry chain and enhance China's "deep-sea access, deep-sea exploration, and deep-sea development" capabilities.
Third, a unique environmental protection and monitoring system was created, which further confirmed the feasibility of natural gas hydrate green development. Independent innovation has formed an environmental risk prevention and control technology system, and built a "Four in One" environmental monitoring system for the atmosphere, water bodies, seafloor and underground. During the trial mining process, there was no leakage of methane and no geological disaster occurred.

According to reports, the realization of natural gas hydrate industrialization can be roughly divided into five stages: theoretical research and simulation tests, exploratory trial mining, experimental trial mining, productive trial mining, and commercial mining. The second round of trial production successfully achieved a gradual leap from "exploration trial production" to "experimental trial production", which was a crucial step in the industrialization process of natural gas hydrates. At present, the second round of trial mining is still in progress, and scientific and technical personnel will conduct necessary test work around accelerating the industrialization of natural gas hydrate exploration and exploitation and implementing productive trial mining.
The China Geological Survey, together with China Petroleum and Natural Gas Corporation, Peking University and other 70 units at home and abroad, has nearly 1,000 business backbones. After more than two years of concentrated research, in October 2019, the second round of trial mining operations was officially launched. The test mining team has overcome difficulties such as no precedent and harsh sea conditions, especially during the critical period of construction, which is the most strenuous stage of the New Crown epidemic prevention and control. The on-site headquarters fully and accurately implemented various prevention and control measures to ensure normal production operations. By 2020 The trial mining was successfully fired on February 17, 2014, and continued to complete the scheduled target mission on March 18.

These technical equipments have broad application prospects in marine resource development, maritime engineering and other fields. They will drive the formation of a new deep-sea technical equipment industry chain and enhance China's "deep-sea access, deep-sea exploration, and deep-sea development" capabilities.
Third, a unique environmental protection and monitoring system was created, which further confirmed the feasibility of natural gas hydrate green development. Independent innovation has formed an environmental risk prevention and control technology system, and built a "Four in One" environmental monitoring system for the atmosphere, water bodies, seafloor and underground. During the trial mining process, there was no leakage of methane and no geological disaster occurred.
According to reports, the realization of natural gas hydrate industrialization can be roughly divided into five stages: theoretical research and simulation tests, exploratory trial mining, experimental trial mining, productive trial mining, and commercial mining. The second round of trial production successfully achieved a gradual leap from "exploration trial production" to "experimental trial production", which was a crucial step in the industrialization process of natural gas hydrates. At present, the second round of trial mining is still in progress, and scientific and technical personnel will conduct necessary test work around accelerating the industrialization of natural gas hydrate exploration and exploitation and implementing productive trial mining.
The China Geological Survey, together with China Petroleum and Natural Gas Corporation, Peking University and other 70 units at home and abroad, has nearly 1,000 business backbones. After more than two years of concentrated research, in October 2019, the second round of trial mining operations was officially launched. The test mining team has overcome difficulties such as no precedent and harsh sea conditions, especially during the critical period of construction, which is the most strenuous stage of the New Crown epidemic prevention and control. The on-site headquarters fully and accurately implemented various prevention and control measures to ensure normal production operations. By 2020 The trial mining was successfully fired on February 17, 2014, and continued to complete the scheduled target mission on March 18.
