摘要
设计了能调节岩心与电极之间夹持力的岩心电阻测量夹具。使用该夹具可直接读出不同夹持力下岩心的电阻 ,并能有效减少电阻测量时因夹持力随机性造成的误差 ,提高室内岩心电阻率的测量精度。实验数据表明 ,因夹持力变化引起的电阻测量误差达 2 0 %~ 30 % ,采用该方法能将这种误差降至 10 %。
Gripping device for measuring core resistivity which can regulate the holding force between the core and electrode is designed. The core resistivity at different holding force may be read directly, error caused by the holding force randomness at resistivity measuring may be reduced effectively and measurement precision of the laboratory core resistivity may be improved when this device is used. Experimental data show that the measurement error of the resistivity caused by the change of the holding force is up to 20%~30%, and the error may be reduced to 10% by using this method.
