    A DISCUSSION ON TECHNOLOGY FOR GAS HYDRATES PRODUCTION IN THE SOUTH CHINA SEA USING GEOTHERMAL AS AN ENERGY SOURCE

    • 摘要: 近年的研究表明南海北部陆坡区发育有底辟构造、海底滑坡以及活动断层带等有利于天然气水合物形成的地质构造环境。受深部地幔上隆的影响,南海整个海区热流背景值偏高,地热资源十分丰富,由此提出了利用地热加热海水,用热激发法分解天然气水合物的设想,并设计了初步的生产工艺。用传统热激发方法开采天然气水合物藏本身需要消耗大量能源,而且效率低下,开采成本太高。在南海利用地热开采天然气水合物藏的工艺大大降低了开采热源输入的成本,具有商业开采的可行性。

       

      Abstract: Geo-tectonic environment of the continental slope of the South China Sea is favorable to the formation of gas hydrates. Diapir structures, submarine slides and active faults are well developed. Due to the thermal effect of deep mantle rising, the South China Sea has a high background value of heat flow, and is rich in geothermal resources. In this paper, an option was proposed to use submarine geothermal as a source to heat seawater for decomposition of gas hydrate. A preliminary process of production is described in the article. Production of gas hydrates by traditional thermal excitation consumes large amount of energy, and the cost is too high. Using geothermal to exploit gas hydrates in the South China Sea with the technology designed in this article is much more cost efficient and feasible.
