Theoretical and Experimental Characterization of Gas Hydrates in Oceanic Sediments

[401010]为建立含天然气水合物海洋沉积物地震性质定量模型提供了资金。这将有助于描绘天然气水合物的分布，估计其体积，解释底部模拟反射体的性质以及区分水合物的形态。该模型还将有助于未来在水合物领域的钻探工作。该模型将基于沉积物的微观结构。该模型将在实验室中通过测量模拟水合物胶结的胶结颗粒材料的压缩和剪切速度来进行测试。＊＊＊

9401010 Nur Funds are provided to develop a quantitative model of the seismic properties of oceanic sediments containing gas hydrates. It will help delineate the distribution of gas hydrates, estimate their volume, explain the nature of bottom simulating reflectors and distinguish among hydrate morphologies. The model will also help in future drilling efforts in hydrate fields. The model will be based on microstructure of sediments. The model will be tested in the laboratory by measurements of compressional and shear velocities in cemented granular materials that simulates hydrate cements. ***
