摘要:
海域水合物成藏条件特殊，其开发技术难度较陆地冻土难度更大。通过对日本三次海域水合物试采过程及取得成果的回顾，分析了日本海域水合物试采过程中采用的试采方法，以及完井防砂、人工举升、地质监测与环境监测等重点技术方案，认为降压法是日本海域天然气水合物最佳的试采方法，其他方法可以作为辅助使用，同时必须解决出砂问题。试采过程中，应运用多种监测方法保证水合物试采的安全性，避免水合物可能引起的地质灾害。该技术可为相关海域水合物开发提供经验。
Abstract:
Because of the special reservoirforming conditions of hydrate in the sea, its development technology is more difficult than that of terrestrial permafrost. Based on the review of the production tests and the results of hydrate three times obtained in Japan, this paper analyses the key technical schemes adopted in the process of hydrate production tests in Japans sea areas, such as well completion & sand control, artificial lifting, geological monitoring and environmental monitoring. It considers that the depressurization method is the best test production method for natural gas hydrates in Japans sea areas, and other methods can be used as auxiliary methods. However, the sanding must be solved at the same time. In the process of production test, various monitoring methods should be used to ensure the safety of hydrate test production and avoid the geological hazards that may be caused by hydrate. This technology can provide experience for hydrate development in related sea areas.
