摘要：As about 99% of the natural gas hydrate (NGH) resources are stored on the seafloor, it is inevitable that in its process of exploration and production, there will be geohazards such as methane leakage, seabed subsidence, ecosystem damage and even landslide. Therefore, a set of integrated systems for environmental monitoring in the process of NGH production has been proposed in the consideration of environmental disasters that may arise in the process of hydrate production. We set up monitoring units from the seabed, water column to wellbore, in order to obtain integrated data concerning environmental effects during the hydrate production, with the aim of an early warning in the event of potential environmental geohazards.
