中文摘要 | 天然氣水合物是由水和天然氣在高壓和低溫條件下形成。天然氣水合物廣泛沉積在高山永凍土層和大陸邊緣深水沉積層中。由於天然氣水合物含有大量甲烷,如果大量開發成功,天然氣水合物將是21世紀最有前景的能源。為促進陸地和海洋領域的天然氣水合物的探勘和開發,從2002年起,中國分別在南海北部的神狐和東沙水域、青藏高原、漠河盆地等地區,全面開發海底盆地和永凍土層的天然氣水合物資源,這3個地區的天然氣水合物儲量分別為68.3、12.5和2.8兆立方公尺,中國天然氣水合物總儲量約為84兆立方公尺。根據2017年的天然氣年消費量2,404億立方公尺,上述探明的天然氣水合物儲量可以滿足中國天然氣需求長達349年。本文目的在於全面回顧中國天然氣水合物資源開發和調查過程中的主要活動和里程碑。 |
英文摘要 | Natural gas hydrate is formed by water and natural gas under the conditions of high pressure and low temperature. Gas hydrate is widely deposited in permafrost in high mountains and in sediment in the deep water of continental margins. Because gas hydrate contains a large amount of methane, if successfully developed in large quantities, gas hydrate is one of the most promising energy resources for the 21^(st) century. Aiming to promote the exploration and development of natural gas hydrate in territorial jurisdiction areas including land and marine fields, beginning in 2002, China has comprehensively developed gas hydrate resources in submarine basins and permafrost areas, such as the Shenhu and Dongsha waters (in the northern South China Sea) and Mohe Basin and the Qinghai-Tibet Plateau, respectively, as well as other regions. The reserves of natural gas hydrate in these three areas are 68.3, 12.5, and 2.8 trillion cubic meters, respectively, and the total natural gas hydrate reserves in China are approximately 84 trillion cubic meters. Based on the annual natural gas consumption rate of 240.4 billion cubic meters during 2017, the aforementioned proven reserves of natural gas hydrate can supply China's natural gas demand for up to 349 years. The purpose of this paper was to comprehensively review the major activities and milestones during the development and investigation of natural gas hydrate resources in China. |
