you are: the Thermal stream in danii
The collection swept also the limestone, used in our researches of a thermal stream, consisted of 30 samples collected on 12 exposures in northern Jutland, and 19 samples of a core from two deep chinks (Гассум-1 and Виндинг-1). All samples before measurements were sated with water in vacuum within at least 24 hours. At high speeds of drilling of a chink are prepared for immediate input of a needle probe. Diameter of a needle probe same as diameter of a drill, and the thin water film serves as a contact material.
From 66 measurements on superficial samples we have received average values for each site and after the weight of measurements has been considered, average value has appeared equal 1,63 yo 0,09 Vt / (м*К). Porosity of rocks was measured also. Average value has appeared equal 42 + 4%, and average values for different sites vary from 37 to 48%. Factors of heat conductivity of a core in comparison with the average value received on a surface. The general increase in heat conductivity with depth which is connected mainly with porosity reduction is marked. Reduction of porosity with depth for limestone and a chalk was observed and at electric karotazhe in some deep chinks; it is supposed, that it is the general feature Danish (verhnemelovyh) adjournment in the Danish subpool.
