岩石核磁共振T2谱与电阻率指数的对应性研究
Correspondence of core nuclear magnetic resonance T2 spectrum and resistivity index
摘要
Abstract
The power function relationship between nuclear magnetic resonance(NMR) T2 specturm and resistivity index was established on the basis of fractal property of core and capillary bundle theory. Quantitative descriptions between pore structure and conducitivity propery were investigated by combination of theory and petrophysical data. The results show that NMR T2 bears favourable power function relationship with resistivity, which decreases with the increase of resistivity inedx. The NMR T2 fitted exponent bears favourable linear relationship with saturation exponent,which increases with the increase of saturation exponent. The corresponence investigation between NMR T2 and resistivity index gives quantitative analysis for Archie parameters, especially for saturation exponent.关键词
