Rock Thermal Conductivity of Natural Gas Hydrate Deposits in the Muli Basin of Chinese Qinghai-Tibet Plateau

摘要

This study reports laboratory measured thermal conductivity values of sandstones from 4 wells (predominantly hydrae exploration boreholes). The objective of the present work is to report the values of the thermal conductivity that were measured in the cores from the borehole that was estimated for the geological formations intercepted by it. The measurements were made on drill cores using the guarded parallel-plate apparatus at a temperature range from 285 to 290 K at Atmospheric pressure. Bulk thermal conductivities of sandstones corrected for in site thermal conditions range between 2.1 and 2.8 W/m/K. In general, the estimated uncertainty of the Effective thermal conductivity measurements is 2%. These data can be used for design of gas recovery form gas hydrate using heat injection technology.
