摘要

Natural gas hydrate is widely distributed in continental slope sediments and permafrost, taken as a potential energy resource due to its gigantic amount. To develop the technologies for the industrial exploitation of natural gas hydrate, several production tests were carried out in permafrost and marine hydrate reservoirs, e.g. tests in permafrost hydrate reservoirs in Mackenzie Delta and Alaskan North Slope (Boswell et al., 2017) in the Antarctic, and those in marine hydrate reservoirs in Nankai Trough, offshore Japan (Yamamoto et al., 2014, 2018), and South China Sea (SCS) (Li et al., 2018; Ye et al., 2020). As encouraged by the results obtained from the production tests, more tests are planned to develop technology for industrial exploitation of natural gas hydrate (Collett et al., 2022). Although production test can be conducted in permafrost hydrate reservoir for cost efficiency, generally it is thought industrial exploitation will be realized in marine hydrate reservoir because it is estimated with over 90% of hydrate resource.
