| 摘 要： | 2008年冬季和2009年夏天首次在我国陆域祁连山冻土区钻获到天然气水合物实物样品。野外直接观察到白色冰状天然气水合物与点火燃烧现象及其他明显的异常现象,如含天然气水合物岩心表面强烈地冒气泡、渗出水珠、没入水中冒出长串气泡、井中释放异常压力气体、密闭条件下解析出异常含量气体、岩心晾干后留下重烃斑迹、残余细蜂窝状构造、伴生晶型完好的菱形自生方解石矿物、热红外低温异常等现象;室内激光拉曼光谱检测到天然气水合物笼状体峰及其包含的烃类气体峰,宏观地球物理测井曲线上显示含天然气水合物岩心段存在明显偏高的电阻率和声波速度异常。祁连山冻土区天然气水合物及其异常现象主要产出在冻土层下130~400 m之间的细砂岩孔隙与裂隙中及泥岩、油页岩、粉砂岩等裂隙中。 |

| Abstract: | Gas hydrate was discovered for the first time on the continent of China,namely in the Qilian Mountain permafrost of Qinghai Province in the winter of 2008 and the summer of 2009.In the field,white ice-like gas hydrate and the burning phenomenon were directly observed.Its obvious relevant anomalies were also recorded.These anomalies include phenomena of strongly bubbling and water seeping on the fresh surface of gas hydrate bearing cores,a chain of bubbles coming from under water when gas hydrate bearing cor... |
