用快中子共振透射成像定量鉴别钻孔岩心中的油和水
Quantitative discrimination between oil and water in drilled bore cores via fast-neutron resonance transmission radiography
摘要：
提出了一种基于快中子共振透射成像技术的地下或水下地质层岩心油水质量分数无损定量测定的新方法。该方法区分水和油的能力源于主要元素成分的中子截面的明确的特定能量依赖性。蒙特卡罗模拟和实验研究的初步结果表明，该技术可以提供一个快速，准确和非破坏性的方法，定量评价的核心流体在厚完整的核心，包括那些致密页岩的使用传统的核心分析方法似乎是值得怀疑的。
英文摘要：
A novel method based on 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.
