JIN Chunshuang, WANG Jiyang. THE PROGRESS IN GEOTHERMAL STUDIES ON GAS HYDRATES[J]. Advances in Earth Science, 2001, 16(4): 540-543.
The researches on gas hydrates have recently become a major focus both at home and abroad. Recently, geothermal studies on gas hydrates have m ade remarkable progress in the following aspects. (1) The relationship between heat flow and bottom simulating reflector (BSR), is mainly used to derive the value of heat flow from the data of BSRs, especially where heat flow measuring point is rare. (2) The research on gas hydrate stability zone, mainly predict the depth to the base of gas hydrate stability zone from the geothermal data, such as sea bottom temperature and geothermal gradient and so on. (3) The gas hydrates thermal properties determination, which is the foundation of geothermal studies on gas hydrate, is usually attained by three ways：in situ measurements, laboratory measurements and derivation from electrical property. (4) The thermal regime during gas hydrate formation and evolution. (5) The application of thermal conductivity in predicting the distribution of gas hydrate in sediments and establishing the relationship with pressure wave velocity. In the paper, a review on these aspects has been given and further study perspectives are pointed out.
