| 摘 要： | 热释光测量在探测陆地或海洋油气方面已显示出良好的应用效果,天然气水合物与常规油气在物源及运移机制上非常相似,可将热释光方法借鉴到天然气水合物的调查研究中。羌塘盆地147件沉积物样品的热释光测定结果表明,该区沉积物热释光具有近似对数正态分布的特征。结合前人研究结果及调查分析认为,该区热释光异常与深部油气或天然气水合物的对应模型为:矿藏上方出现热释光高值异常。研究区热释光高值异常出现2处集中分布区域,大致指示深部油气或天然气水合物藏的位置。研究结果对羌塘盆地油气或水合物的进一步调查研究有重要的参考价值。 |

| Abstract: | Thermoluminescences of sediments have been used in exploring oil and gas both on land and on marine,which has achieved great success.Owning to similarity between oil/gas and gas hydrate in origin and mechanism of migration,thermoluminescences could be used in exploration and exploitation of gas hydrate.147 samples of sediments were collected from the Qiangtang Basin,Qinghai-Tibet Plateau for thermoluminescence survey.The results of thermoluminescence show that it is charactered by logarithm normal distribution and distinct abnormity.By integrating scientists' achievement and our survey results,we concluded that the above thermoluminescence abnormities should be a high value abnormity of hydrate mineral resources.The thermoluminescence abnormities are concentrated in two areas,which indicates the approximate position of deep oil/gas or gas hydrate reservoirs,and has a great significance for the further research. |
