孔隙结构对电阻率影响机理研究
STUDIES ON THE INFLUENCING MECHANISMS .OF PORE STRUCTURES ON RESISTIVITIES
摘要
Abstract
The influences of the pore structures on the electric properties are mainly transited by the index of the pore structures (m). The reservoir resistivity is thought to by dropped 43% when m reduced from 2. 0 to 1. 7 under the conditions of 12. 5% porosity and the same other terms; when m is 1. 44, the dropped value is up to 67. 5%. The experimental data analyses of mercury injecting method show that the value m is impacted by the pore structures of the rocks, when the radium of the medium value decreased, the corresponding value m is also reduced; the more the interstitial matter is, the easier the better electricity-conducting network with well-developed micro-fine capillaries can be formed in pores and throats, thus the reduced overall resistivity of the reservoir rocks will be caused. When the porosity is as same as the water saturation, the reservoir resistivities will be dropped with the decrease of the value m.关键词
