摘要
天然气水合物作为一种高效、清洁的新能源,已经引起世界广泛关注,由于其不稳定性,采用的钻探取心装置必须具备保真功能。简要介绍了国内外4种天然气水合物取心装置及国内取心工具研究进展,叙述了胜利石油管理局钻井工艺研究院承担国家"863计划"重大专项"天然气水合物钻探取心关键技术"采取的取心工具方案。
As a new kind of high efficiency and clean energy resource, natural gas hydrate has extensively attracted attentions all around the world. The device used for sampling the natural gas hydrate core must possess the properties of warm preservation and pressure preservation due to its instability. The developing situations at home and abroad for sampling of the natural gas hydrate, a new preliminary concept for sampling of the natural gas hydrate were introduced. The coring tool research project included in the ＂Key coring technology for natural hydrate＂ was described, a major project of national ＂863＂ plan.
