Gas hydrate reservoir types, characteristics and development methods

  • 摘要: 天然气水合物作为潜能巨大、资源量丰富、燃烧值高的未来新能源,但由于其特殊的物理力学性质和赋存状态,经济开采技术仍面临诸多难题。本文以全球勘探发现存在天然气水合物的地区为基础,介绍了全球主要水合物的海陆资源分布及开采难易程度;以主要影响天然气水合物开采方式选择因素为基础,分析了天然气水合物在地层中的赋存类型、成藏模式和储层分类方法;以全球已开展的天然气水合物试采项目为基础,对比分析了现有多种天然气水合物开采方法的优缺点和适用条件;在现有开采方法条件下,为不同赋存状态、成藏模式和储层分类的天然气水合物选择出适合的开采方法,为建立完整的天然气水合物开采技术体系和未来实现商业化开采提供参考。

     

    Abstract: Natural gas hydrate is a new type of energy with huge resource potential and high combustion value. Due to its special occurrence and physical-mechanical properties, economic development of the resources still faces many problems and challenges. The distribution patterns of gas hydrate resources in the sea and on the land as well as the difficulties ever encountered in the exploitation of some major hydrate deposits in the world are studied in this paper as cases. Based on the mining methods selected, the occurrence, accumulation models and reservoir classification of gas hydrate underground are analyzed and discussed. Taking some pilot hydrate production projects as examples, various existing natural gas hydrate mining methods are compared and analyzed for their advantages, disadvantages and application feasibilities. Based upon the above discussion, suitable mining methods are selected and recommended. The paper may provide a reference for establishing a complete natural gas hydrate mining technology system for realization of commercial exploitation in the future.
