岩心导热系数测定技术研究

DETERMINATION OF THERMAL CONDUCTIVITY IN CORES

本文论述了国产GRD—Ⅱ型快速导热仪测试岩心导热系数的原理、方法、条件和制样技术。通过研究确定了松辽盆地北部不同地区、不同岩心导热系数变化的范围及其与有关地质特征的关系。并对仪器的精度、稳定性及不同岩性对测试结果的影响进行了分析和评价。

<ABSTRACT>: This paper describes the principle, method, condition of GRD - ? Rapid Thermal Conductivity Unit for measuring core samples and the technique of sample making. The variation range of thermal conductivity of different cores and different areas in the north of Songliao basin and the relation ship with certain geology characteristics is determined. The accuracy, stability and effect of different lithology on measurement results is analyzed and e-valuated.
