Research status and prospects of increasing production from gas hydrate reservoirs

As a potential energy with huge resource reserves, gas hydrate plays an important strategic role in ensuring national energy security, but low mining productivity has always been one of the key bottlenecks restricting its industrialization. Breaking through the constraints of mining productivity will help accelerate the industrialization process of gas hydrates. Therefore, to systematically summarize the current research status of increasing the production from hydrate reservoirs at domestic and abroad will help guide subsequent research on the field trial and even commercial development of gas hydrate. Based on briefly analyzing conventional hydrate mining methods and research status of the field production trials on hydrates, this paper focuses on the mining methods and casing program designs for stimulation production, and summarizes the advantages and disadvantages of different stimulation schemes in detail. Additionally, this paper provides corresponding research suggestions, and looks forward the future research directions of increasing the production of hydrate reservoirs, so as to provide new ideas and references for subsequent research of the industrialization of hydrates.
