2013年8月11日,“祁连山及邻区天然气水合物资源勘查”项目组时隔2年后再次在青海省天峻县木里镇DK-9科学钻探试验井中成功钻获天然气水合物实物样品。此次钻获的样品主要产于细砂岩及泥岩、油页岩裂隙中,位于井深188.20～209.45m,单层厚度超过20m。DK-9孔位于首次发现天然气水合物样品的DK-1钻孔东南方向约450m处,是2013年7月依据对该区地质、地球物理、地球
On August 11, 2013, the project team of “Exploration of Natural Gas Hydrate Resources in the Qilian Mountains and Adjacent Regions” succeeded in drilling gas hydrates once again at the DK-9 Scientific Drilling Well in Muli Town, Tianjun County, Qinghai Province, two years later Physical samples. The samples were mainly produced in the fine sandstone and mudstone, oil shale fissures, located in the depth of 188.20 ~ 209.45m, monolayer thickness of more than 20m. The DK-9 hole was located about 450m southeast of the DK-1 borehole where gas hydrate samples were first discovered. Based on a survey of the geology, geophysics,
