In the future, the world will enter an energy society. The success of China's combustible ice mining is an important sign of China's overall national strength. How much do you know about combustible ice? How much combustible ice does China have?
Ye Jianliang, deputy chief engineer of China Geological Survey Bureau and director of Guangzhou Marine Geological Survey Bureau and chief commander of pilot production site headquarters, said that since May 10, the pilot production has lasted for 60 days, with a cumulative gas production of more than 300000 cubic meters, and many major breakthroughs have been made, including the longest continuous gas production time, the largest total gas production, air flow stability, environmental safety, etc., creating gas production World record for duration and volume.

What is combustible ice?
Natural gas hydrate, also known as combustible ice, is a kind of ice like crystal substance formed by water and natural gas under high pressure and low temperature. It has the characteristics of high combustion value, small pollution and large reserves. It is regarded as a strategic alternative energy for oil and natural gas in the future by all countries. Its successful pilot production is of great significance to promote energy security and optimize energy structure in China.
The trial mining area is located in the sea area of Shenhu, 320km southeast of Zhuhai City. On March 28, the first trial production well was drilled, and on May 10, at 14:52, the ignition was successful. Natural gas was extracted from a gas hydrate deposit 203 meters to 277 meters below the sea floor with a depth of 1266 meters. As of 14:52 on July 9, the average daily production of this trial production is more than 5000 cubic meters, with a maximum production of 35000 cubic meters / day and a maximum methane content of 99.5%. 6.47 million groups of scientific test data were obtained, which accumulated a lot of data for the follow-up scientific research.

The success of this trial production is the first time in China and the first time in the world to realize the safe and controllable production of shale, silt and sand natural gas hydrate, which accounts for more than 90% of the world's resources and is the most difficult to develop. "The results of this pilot production show that the theory, technology, engineering and equipment of natural gas hydrate production in China are leading in the world, and the advantages are still expanding. 'ye Jianliang said. (this article is exclusively compiled by WYH, editor of sihai.com. If you need to reprint it, please indicate the source and source.

Li Jinfa, deputy director of China Geological Survey Bureau and deputy leader of natural gas hydrate trial production coordination leading group, said that in the future, the exploration of natural gas hydrate resources will be further strengthened to provide resource basis for industrialization; at the same time, the research of theory, technology, engineering and equipment will be strengthened to provide technical preparation for industrialization, and rely on scientific and technological progress to protect marine ecology and provide for industrialization At the same time, it studies the normative documents and industrial policies of exploration and development management to provide relevant guarantee for industrialization.
According to the calculation, the resource potential of China's combustible ice is about 80 billion tons of oil equivalent, which is more than 1.25 times of Saudi Arabia's currently proved oil reserves. The land prospect resource is at least 35 billion tons of oil equivalent, which can be used by China for nearly 90 years.
