The petrophysical and petrothermal characterization of the sedimentary succession of the Oliana anticline in the Southern Pyrenees has been performed on the basis of mineral density, connected porosity, permeability, P-wave velocity and thermal conductivity measurements of rock samples distributed along this anticline. This dataset was used to explain: (I) the variability of petrophysical rock properties along the Oliana anticline, (II) the distribution of thermal conductivity along the sedimentary units of the anticline, (III) the relationships between the fold and petrology concerning the mineral density, connected porosity, permeability, P-wave velocity and thermal conductivity of rocks and (IV) the tectonic and diagenetic controls underlying the observed relationships, as described in the research article: "Petrological, petrophysical and petrothermal study of a folded sedimentary succession: the Oliana anticline (Southern Pyrenees), outcrop analogue of a geothermal reservoir - Global and Planetary Change Journal (2023)". This contribution presents here the raw and statistical datasets used to discuss the potential of the Oliana anticline as a geothermal reservoir analogue and also includes an extended methodological section that proposes a new procedure to measure the thermal conductivity of highly heterogeneous coarse-grained sedimentary rocks using the Modified Transient Source Plane (MTPS) method on a TCi C-Therm thermal analyzer. These complete datasets can be used to better discuss and understand the principal limitations of outcrop analogue studies applied to unconventional geothermal reservoirs in foreland basins on the basis of the analysis of rock petrophysical and petrothermal properties. Furthermore, the data obtained in the Oliana anticline can be used to understand the structural, diagenetic and petrological factors that can modify the petrophysical and petrothermal properties of rocks and to discuss the potential of foreland basin margins to be used as geothermal reservoirs, comparing the data obtained in Oliana with studies developed in similar geological settings worldwide.
基于沿南比利牛斯山脉奥利阿纳背斜分布的岩石样品的矿物密度、连通孔隙度、渗透率、纵波速度和热导率测量结果，对该背斜沉积序列进行了岩石物理和岩石热学特征分析。该数据集用于解释：（I）奥利阿纳背斜岩石物理性质的变异性；（II）背斜沉积单元内热导率的分布；（III）褶皱与岩石学之间关于岩石的矿物密度、连通孔隙度、渗透率、纵波速度和热导率的关系；以及（IV）如研究论文《褶皱沉积序列的岩石学、岩石物理和岩石热学研究：奥利阿纳背斜（南比利牛斯山脉），地热储层的露头模拟——全球与行星变化杂志（2023）》中所述的观察到的关系背后的构造和成岩控制。本论文展示了用于讨论奥利阿纳背斜作为地热储层模拟潜力的原始和统计数据集，还包括一个扩展的方法部分，该部分提出了一种新程序，使用TCi C-热分析仪上的改进瞬态源平面（MTPS）方法测量高度非均质粗粒沉积岩的热导率。这些完整的数据集可用于在分析岩石岩石物理和岩石热学性质的基础上，更好地讨论和理解应用于前陆盆地非常规地热储层的露头模拟研究的主要局限性。此外，在奥利阿纳背斜获得的数据可用于理解能够改变岩石岩石物理和岩石热学性质的构造、成岩和岩石学因素，并通过将在奥利阿纳获得的数据与全球类似地质环境中开展的研究进行比较，来讨论前陆盆地边缘用作地热储层的潜力。
