EVALUATION OF LITHOPHYSAL CONDUCTIVITY, DIFFUSIVITY, AND POROSITY MEASUREMENTS USING THE REKA METHOD

摘要

A method is presented, based on the NUFT and REKA V1.1 software packages combination, tornstudy the nature of non-steady-state heat flow during a single-borehole REKA thermal probernthermophysical measurement in solid as well as lithophysal rock formation. The results prove thernprinciple of the REKA method application in lithophysal formation. The numerical evaluationrnresults, based on the use of two qualified software packages, show that the presented REKArnprobe arrangement is correctly modeled and that the effective heat conductivity and thernlithophysal porosity can be evaluated correctly using the REKA probe method.
