  • In order to understand the frozen soil layer structure at Qiangtang basin, the practice of MRS has been carried out in two study area of Qiangtang basin. Combined laboratory tests and actual field data, permafrost basis cannot cause the instrument response, which is one of the important evidence in dividing permafrost and detecting hydrate. Near the drilling sites, acquisition by NMR signal, analysis considered natural gas hydrate in the steady state, decomposition of produced water or liquid hydrocarbon, formed the coexistence of water-gas hydrate-three-phase situation, caused the NMR reaction. Practice indicates that MRS method can be used to detect distribution of the permafrost and tundra, which has a very important scientific significance and application value.
