| [摘要]海洋天然气水合物占全球水合物总储量的99%,海洋天然气水合物大部分沉积在海底浅
层没有良好的覆盖层,无法采用开采传统油气资源的方法进行开采。为了开采海底浅层天然气水合物,
分析了海洋天然气水合物的存在类型及地质特征,探讨了目前开采海洋天然气水合物的理论方法及局
限性。根据海底天然气水合物成矿的地质特点及水合物的物理特性,提出了以水力输送技术为主要理
论的海洋浅层天然气水合物开采方法。该方法克服了其他方法开采海底天然气水合物面临的技术困
难,为海洋天然气水合物的开采提供了技术基础及理论支撑。 |

| Abstract:In the world about 99 percent gas hydrate reserves is marine gas hydrates, and the vast majority of gas hydrates is hosted in seafloor sedi鄄
ments, which has not good/ solid cover layers. All these gas hydrates can not be exploited by using traditional mining methods of oil and gas wells. In or鄄
der to exploit marine gas hydrates from shallow depth of seafloor, the existence state and geological features of marine gas hydrates were studied and the
theory, techniques and the limitations of the current marine gas hydrate exploitation were discussed. According to geological characteristics and physical
properties of marine gas hydrates, we propose a new technique to extract natural gas from marine gas hydrates, which is based on the theory of hydraulic
mining technology. This method overcomes the technical difficulties of other methods to exploit marine gas hydrates and provides a technical foundation for
extracting gas form marine gas hydrates. |
