| Summary: | Introduction. Marine gas hydrates are an unconventional resource of natural gas that is stored in deep-sea sediments in a solid state. It has a wide distribution and large reserves, and is also considered as an important alternative energy source for oil and natural gas in the future. The United States, Japan, China and other countries have introduced relevant laws and regulations regarding this energy source and have conducted a sufficient number of scientific studies. Currently, gas hydrate extraction technologies on the Chinese shelf mainly include the pressure reduction method and the solidphase fluidization method. These methods have their advantages and disadvantages, but they are difficult to meet the needs of commercial mining.Materials and methods of research. Gas hydrates, commonly known as «combustible ice», are mainly found in the sediments of the seabed and permafrost on land. After decomposition, they can form gases such as methane, which is a clean energy source with rich resources and various countries consider it as an important alternative energy source in the future. However, traditional natural gas resources in China are struggling to meet the demand for clean energy as a result of economic development, and the extraction of gas hydrates promises to be an effective way to solve this problem. Thus, the study of gas hydrates can not only contribute to the early commercial exploitation of gas hydrate resources in the South China Sea, but also allows us to hope for a reduction in the cost of deep-sea traditional natural gas resources.The results of the study and their discussion. The article provides a detailed description of each method of gas hydrate extraction technology in China with a comparative analysis of their advantages and disadvantages of application in practice. Tests of gas hydrates in the South China Sea with an assessment of their results are also given as an example.Conclusions. The article provides recommendations on the issue of gas hydrate production in the South China Sea. Recommendations are given on the need for simultaneous research of traditional technologies and breakthrough production technologies, as well as improving the technology of interpretation and evaluation of gas hydrates in the sea area, with subsequent cost reduction in terms of the entire life cycle and, as a result, the study of key equipment and technologies for deep-sea operations. |
