Abstract：The permafrost regions of the Tibetan Plateau are distributed in the middle latitudes of China,where the gas hydrate is different from the gas hydrate in sea area and polar permafrost area in existing environment and basic characteristics. The lack of effective exploration technology has become the major technical bottleneck that restricts the investigation and evaluation of natural gas hydrate resources in permafrost regions of China. Supported by National 863 Program, Special Research Project of Ministry of Land and Resources and National Special Project of Gas Hydrate, the authors studied the development of key technologies of natural gas hydrate exploration in the permafrost regions of China. The prorate exploration methods for China's terrestrial gas hydrate exploration in permafrost areas have been initially established, which include the high resolution seismic method, the audio magnetotelluric sounding technology, the ultra-deep ground penetrating radar (GPR) technology, geochemical exploration technology and integrated geophysical logging technology. The seismology and electromagnetism identifications of gas hydrate reservoir have been found, the effective index of hydrate geochemical exploration is optimized, and the logging identification technology and reservoir parameter evaluation technology of gas hydrate reservoir are developed. An effective combination method for geophysical and geochemical exploration and a comprehensive geophysical and geochemical exploration model have been tentatively established in permafrost regions. The favorable area of gas hydrate accumulation is predicted, and several gas hydrate reservoirs have been found in the well suggested by the authors, which shows that the validity of methods proposed by the authors are tentatively tested and applied. The research results have great significance for promoting the progress of gas hydrate exploration and for supporting the exploration and development of natural gas hydrate resources in permafrost regions of China.
