Nuclear magnetic resonance (NMR) has emerged as an essential method for appraising gas-shales, quantifying their petrophysical properties, classifying their fluid types, and discerning their productivity. Comprehensive measurement campaigns, as well as reliable thermal-heating experiments, are required to fully understand the NMR mechanism of shale and to further develop future gas-shale exploitation strategies. NMR signatures from individual matrix components, which comprise shale, are investigated to gather data to better estimate its petrophysical parameters. Subsequently, we perform T₁ and T₂ measurements of kerogen, solid bitumen, and clay minerals. Next, we analyze the temperature effect on the NMR signal interpretation of different compositions of gas-shale samples in detail, coupled with the position of clay minerals and solid bitumen from the T₁-T₂ mapping. A shale plug sample was quantified by the NMR T₁-T₂ relaxation signals under initial conditions and different temperature conditions of 110 °C, 250 °C, 450 °C, and 650 °C. The fluid volume significantly decreased as the temperature increased. The organic matter maturity changed at 450 °C and 650 °C. According to a thermal-heating experiment with powdered clays, we obtained the hydroxyl group and crystal water signals and determined the critical temperature for different dried types of water in clay mineral. It is reasonable to infer that deconvoluting the entire shale sample into different components can further determine the NMR relaxation mechanisms. The ultimate goal of this project was to develop a holistic methodology to understand the NMR mechanisms of isolated components and to assess the positions of kerogen, solid bitumen, illite, kaolinite, smectite, and chlorite from T₁-T₂ mapping. This work contributes to the fundamental understanding of shale formations by quantifying the NMR relaxation mechanisms of various constituents in shale and provides implications for shale rock evaluations.

核磁共振（NMR）已成为评估气页岩，量化其岩石物理性质，对其流体类型进行分类并识别其生产率的基本方法。需要全面的测量活动以及可靠的加热实验，才能充分了解页岩的NMR机理并进一步发展未来的气页岩开发策略。研究了包括页岩在内的各个基质组分的NMR特征，以收集数据，以更好地估算其岩石物理参数。随后，我们执行T ₁和T ₂测量干酪根，固体沥青和粘土矿物。接下来，我们详细分析了温度对气页岩样品不同成分的NMR信号解释的影响，并根据T ₁ -T ₂映射分析了粘土矿物和固体沥青的位置。通过NMR T ₁ -T ₂对页岩塞样品进行定量在初始条件和110°C，250°C，450°C和650°C的不同温度条件下的松弛信号。随着温度升高，流体体积显着减少。有机物成熟度在450°C和650°C时发生变化。根据对粉状粘土的热加热实验，我们获得了羟基和结晶水信号，并确定了粘土矿物中不同干燥类型的水的临界温度。可以合理推断，将整个页岩样品解卷积为不同的组分可以进一步确定NMR弛豫机理。该项目的最终目标是开发一种整体方法，以了解分离出的组分的NMR机理，并评估T中干酪根，固体沥青，伊利石，高岭石，蒙脱石和绿泥石的位置。₁ -T ₂映射。这项工作通过量化页岩中各种成分的NMR弛豫机制，有助于对页岩形成的基本理解，并为页岩的评估提供了启示。
