天然气水合物及其地球物理识别方法的研究进展

GAS HYDRATE AND ITS GEOPHYSICAL RECOGNITION STUDIES

天然气水合物的研究涉及地球物理、地球化学、地质等多种学科 ,其中地球物理方法在天然气水合物的探查和研究中发挥着重要的先导作用。对水合物的类型及物理化学性质、自然赋存和成藏条件、资源评价、勘探开发手段以及水合物与全球变化和海洋地质灾害的关系等进行了综合论述 ,较为系统地论述了天然气水合物及其地球物理识别方法研究的进展 ,并结合中国水合物探查研究的实际 ,初步预见中国南海北部海域具有水合物成藏的良好前景。

The studies of gas hydrate involve Geophysics,Geochemistry,Geology,and so on.Now,the geophysical recognitions are dominant in the discovery and research of gas hydrate.The types,physical and chemical properties,natural deposit condition,evaluation,exploration and development measurements,and the relationship between gas hydrate and global changes and marine geological disasters were discussed comprehensively.This paper reviewed systematically the properties and characteristics of gas hydrate and the developments of its geophysical recognitions.Combining with the practice of some preliminary research results,it is found that the northern area of the South China Sea is favorable for the formation of gas hydrate.
