Recently, the national key research and development plan led by Guangzhou Marine Geological Survey - Strategic international science and technology innovation cooperation key special project "Joint Research on natural gas hydrate exploration and development technology" successfully passed the comprehensive performance eva luation organized by the Ministry of Science and Technology. The acceptance expert group believes that the project results have generally achieved independent innovation and localization of core key technologies, some technologies have filled the gaps at home and abroad, and further improved the high-precision exploration and eva luation technology system of natural gas hydrate.

The project focuses on serving the major needs of the industrialization of natural gas hydrate in China. Led by Guangzhou Marine Geological Survey, the project is jointly led by Russia's St. Petersburg State University of Mining and Technology, Ukraine's National Dnipr University of Technology, China University of Geosciences (Wuhan), Institute of Exploration Technology of Chinese Academy of Geological Sciences, Nankai University, Jilin University and other 9 domestic and foreign advantageous scientific and technological forces. Focusing on the key technical problems that need to be solved in the exploration and development of natural gas hydrate in the sea area, such as accurate locking of ore body, fast and accurate acquisition of reservoir parameters, and safe and efficient exploitation of natural gas hydrate, the project has lasted for four years. It has successfully developed a high-precision small three-dimensional seismic exploration system for natural gas hydrate, a new sampling system for natural gas hydrate, an electromagnetic heater for efficient exploitation of natural gas hydrate, a new reservoir transformation reagent and a supporting injection apparatus, and each system has achieved innovative breakthroughs and technological iterations in terms of structural design, performance indicators and operational efficiency. Among them, the high-precision small three-dimensional seismic exploration system and the new gas hydrate sampling system have been successfully demonstrated and applied in the northern part of the South China Sea, realizing the transformation of technological research and development achievements into real productivity.

The project team has overcome adverse factors such as the COVID-19 pandemic, actively built an international exchange and cooperation platform, built a new model of international science and technology cooperation featuring interdisciplinary integration, intellectual property co-construction and sharing, and the integration of government, industry, university, research and application, formed a number of technical cooperation achievements, and cultivated a technology research and development team with an international perspective. The project results are of positive significance to better play the innovative leading role of international cooperation projects, serve the industrialization exploration and development of natural gas hydrate and the "Belt and Road" initiative.
