| 摘 要： | 天然气水合物是目前寻找新型替代能源的热点之一，其勘探、开发和利用的科学与技术是当前面临的重大课题。除地球物理方法可对天然气水合物定位外，地球化学勘探也是寻找它的重要手段。天然气水合物的几种地球化学勘探方法分别利用其直接标志和间接标志。直接标志包括烃类气体含量测定等；间接标志包括孔隙水离子浓度异常、同位素地球化学异常、标志性矿物(标型矿物)及沉积物热释光分析等方法。

| Abstract: | Natural gas hydrates is thought to be an important energy resource in the 21st century. Theories and technologies regarding to the prospecting and exploitiation are great challenges we face today.Beside geophysical methods, geochemical methods are also the important methods in exploiting gas hydrates. Here, several geochemical methods in prospecting natural gas hydrates are presented.The direct methods include the determination of contents of hydrocarbon and so on and the indirect methods include the identification of pore water ionic concentration anomalies, isotopic geochemical anomalies, the sieving of typical minerals and thermoluminescence analysis of sediments, etc.Finally,suggestions are proposed regarding to the development of geochemical exploration techniques for natural gas hydrates. |
