The combustible ice is abundant in storage, wide in distribution, efficient and clean, and wide in commercial development prospect, and researchers use the combustible ice as the first choice of strategic backup energy. Geological survey experts show that the storage capacity of combustible ice in China is high and higher than that of conventional natural gas resources, and the combustible ice has the condition of becoming clean energy in the future. Therefore, the research on combustible ice, particularly the exploitation of combustible ice, has important strategic significance on future energy and is also an important future scientific research direction.
Due to the unique advantages of combustible ice, the characteristics of abundant reserves, wide distribution and the like, a heat wave has been raised about the exploitation work of combustible ice, and investigation shows that at least 30 countries and regions research combustible ice. Generally speaking, the mining of foreign combustible ice is in the experimental simulation trial mining stage, the detection and identification technology is relatively mature, and the problem to be solved in the aspect of safety is still urgent. In recent years, countries such as japan, the united states, germany, india, and the like have successively made detailed development routes of combustible ice, and incorporated it into the national energy source long-term development program. Significant progress has been made in japan and the united states in the field of combustible ice, and in particular japan, which is internationally recognized as the first country in the world to achieve offshore production of combustible ice. Compared with foreign countries, the development of domestic combustible ice is relatively delayed, and currently, the combustible ice is mainly in the investigation stage due to the limitation of technology and technology. In 2004, the natural gas hydrate research center was established at the Guangzhou energy institute of Chinese academy of sciences. Meanwhile, the Zhongde scientists detected a "Jiulong methane reef" of about 430 km 2. In 2005, a combustible ice simulation system was successfully developed. In 2006, a combustible ice fidelity sampler is developed and a relevant simulation experiment is performed, and the geological characteristics of a natural gas hydrate development area are examined in the south-east-sand-west-south sea area in the north of the south sea. In 2007, the combustible ice is successfully drilled for the first time in 2008 of the Shenhu sea area in the north of south China sea, and the combustible ice substance is successfully extracted in the north of south China sea by using the self-researched ocean number six. Meanwhile, the drilling work of 'combustible ice' in the Qilian mountain frozen soil area of Qinghai province in China is also progressed, and the fact that China has 'combustible ice' in the land is proved. In 6 months in 2009, the 'combustible ice' (natural gas hydrate) samples were successfully drilled on south foot of keelian mountain in Qinghai-Tibet plateau, so that China became the country where natural gas hydrate samples were drilled in alpine frozen soil areas for the first time and also became the country where natural gas hydrate samples were drilled in land frozen soil areas after Canada, USA and Russia.
Generally speaking, the exploitation of combustible ice in China mainly needs to solve the problem of difficult exploitation, and the key of the difficult exploitation lies in the huge seawater pressure in the deep sea water, and whether the pressure of the deep sea water can be reduced is the most important aspect of whether the combustible ice can be successfully exploited.
