天然气水合物生成与分解实验检测技术进展

天然气水合物作为新能源已受到世界的关注，各个国家都在进行天然气水合物的模拟实验研究。着眼国内外部分水合物模拟实验系统，针对水合物生成、分解检测单元进行了研究，目的在于掌握各种检测技术的应用特点和优缺点，指导水合物实验系统的建造和完善。通过分析大量文献发现,传统水合物检测方法造价低，但精度也低；光学检测虽然造价较低、性能较好，但仅可对可视釜进行检测研究；声学与电学检测技术虽然具有很好的性价比，但不能够生成直观图像；CT技术和核磁共振成像技术（MRI）是首选的实验检测技术，它们可以完成高精度的实验研究，缺点是价格较高。研究结果在大连理工大学水合物实验室的筹划和建设过程中起到了积极的指导作用。

PROGRESS ON THE EXPERIMENTAL DETECTION TECHNOLOGY OF GAS HYDRATE FORMATION AND DECOMPOSITION

Natural gas hydrate as a new energy has always been highly concerned by many countries in the world and laboratory test studies have been conducted on the simulation of natural gas hydrate. Based on some different laboratory systems，this study focused on the detection technology of hydrate formation and decomposition so as to get a full knowledge on all different detection technologies with various advantages and disadvantages， which will help build up and complete the whole system of laboratory. After review on huge numbers of literature，this study finds out that those traditional detection technologies cost lower but without a higher accuracy；optical detection costs lower with a good property but is limited to visible vessels；acoustic and electronic detection technologies are very good but not able to generate visual images. The CT and MRI technology are the preferred methods which will complete the high precision experimental studies with high cost. This study results play an important role of reference for the designers to complete the construction of the Natural Gas Hydrate Laboratory of Dalian University of Technology.
