A novel method utilizing the Fast Neutron Resonance Transmission Radiography is proposed for non-destructive, quantitative determination of the weight percentages of oil and water in cores taken from subterranean or underwater geological formations. The ability of the method to distinguish water from oil stems from the unambiguously-specific energy dependence of the neutron cross-sections for the principal elemental constituents. Monte-Carlo simulations and initial results of experimental investigations indicate that the technique may provide a rapid, accurate and non-destructive method for quantitative evaluation of core fluids in thick intact cores, including those of tight shales for which the use of conventional core analytical approaches appears to be questionable.
提出了一种利用快中子共振透射射线照相术的新方法，用于无损定量测定取自地下或水下地质构造的岩心中油和水的重量百分比。该方法区分水和油的能力源于主要元素成分的中子截面具有明确特定的能量依赖性。蒙特卡罗模拟和实验研究的初步结果表明，该技术可为厚完整岩心中的岩心流体定量评估提供一种快速、准确且无损的方法，包括那些传统岩心分析方法的应用似乎存疑的致密页岩岩心。
