It has always been the focus of researchers to accurately identify gas hydrate location. Geophysical prospecting is a widely used method for gas hydrate exploration, which has high credibility, especially seismic exploration technology is most generally used. In our study, we analyze the different physical properties of gas hydrate and other minerals bearing in unconsolidated marine sediments based on the effective medium theory. Then, a new attribute is put forward to discriminate gas hydrate. The logging data in the Dongsha area of the South China Sea and the Hydrate Ridge along the Oregon continental margin are applied to validate this method. Our test results are basically in line with actual situation, which provides a new approach in hydrate identification.

鉴定海洋沉积物中天然气水合物的新方法

准确地确定天然气水合物的位置一直是研究人员的重点。物探是天然气水合物勘探的一种广泛使用的方法，具有较高的可信度，尤其是地震勘探技术最为普遍。在我们的研究中，我们基于有效介质理论分析了未固结海洋沉积物中含天然气水合物和其他矿物的不同物理性质。然后，提出了一种新的属性来区分天然气水合物。应用南海东沙地区和俄勒冈大陆边缘水合物岭的测井数据对该方法进行了验证。我们的测试结果基本符合实际情况，为水合物鉴定提供了一种新方法。
