页岩岩芯复电阻率频散特征主要影响因素的实验研究
Experiment research of the main influence factors of shale sample complex resistivity dispersion characteristics
摘要
Abstract
The major influence of rock complex resistivity and the dispersion characteristics are pore water salinity ,porosi‐ty ,permeability ,temperature ,and anisotropy ,etc ;and for shale rocks is also closely related to the TOC content .In the ex‐periment we measured 59 shale samples of complex resistivity and analyzed the influence of different salt saturation ,anisotropy and the content of TOC on shale complex resistivity and the dispersion property of two wells .We find that the complex resis‐tivity and chargeability of shale decreases with the increase of salt saturation ;and has a large difference in the vertical and par‐allel to the direction of the interface layer ,the anisotropy is obvious ;Besides ,the complex resistivity of shale has negative cor‐relation with the TOC content .The experimental result provides valuable information for establishing the shale reservoir com ‐plex resistivity model and explorating and comprehensive evaluating the shale reservoir by electromagnetic prospecting technolo ‐gy .关键词
