DETECTION AND TESTING TECHNIQUES IN GAS HYDRATE EXPERIMENTS
-
摘要: 在多孔介质中进行天然气水合物实验,必须选择实用又有效的探测技术。重点介绍超声、电阻和时域反射(TDR)3种探测技术在水合物实验中的应用情况。近年来现代分析测试技术的引进,使得水合物的研究更加精细和直观。简要介绍激光拉曼光谱(LRS)、核磁共振(NMR)、X射线衍射(XRD)、X射线计算机层析扫描(XRCT)和高压差示扫描量热(DSC)等分析测试技术在水合物上的应用。Abstract: Practical and effective techniques are required for gas hydrate experiments in porous media. Ultrasonic, resistance and TDR detection techniques and their application in gas hydrate experiments are introduced in this paper. The applications of Laser Raman Spectroscopy,Nuclear Magnetic Resonance Spectroscopy,X-ray Diffraction,X-ray Computerized Tomography and High Pressure Differential Calorimetry and their use in gas hydrate experiments are also briefly introduced.
