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. ***

9401010努尔基金用于开发含有天然气水合物的海洋沉积物地震性质的定量模型。它将有助于圈定天然气水合物的分布，估计其体积，解释模拟海底反射层的性质，并区分水合物的形态。该模型还将有助于未来水合物油田的钻探工作。该模型将以沉积物的微结构为基础。该模型将在实验室通过测量模拟水合物水泥的胶结颗粒材料中的压缩和剪切速度进行测试。***
