Abstract

Measurements of thermal conductivity were taken under normal conditions in dry and waterlogged samples of typical rocks from the Kola series, using a section from borehole SG - 3. The measurements were carried out by 2 methods - non-contact, based on a mobile source of thermal energy, and 2 - contact thermal probing on the surface of the sample. It was established that water - logging has a considerable effect on the value of lambda and a close connection was noted between the effect of water - logging and the structure of the rocks. The thermal conductivity of dry and waterlogged rocks is very variable and it is difficult to distinguish the types of rocks from the values of lambda. An attempt was made to correlate the value of lambda with the density of the rocks and the SiO2 content, but no linear correlation was established. Anisotropy was revealed in lambda which correlates in general with elastic anisotropy. -translated by P.Cooke
