Integrated sedimentological, diagenetic and structural analyses have been carried out on microporous and tight Urgonian (Barremian – Aptian) limestones in a study area in SE France in order to understand the influence of diagenetic changes and structural deformation on the spatial distribution of reservoir properties. A diagenetic history for the carbonates was established and was divided into phases which correspond to episodes of regional geodynamic activity. Petrographic (optical, SEM and cathodoluminescence microscopy), structural and geochemical (δ¹⁸O, δ¹³C) studies were carried out to characterize the cement phases in the carbonates, especially micrite and blocky calcite, and to investigate their relationship with episodes of fracturing.

法国东南部巴勒莫期-二叠系乌格里蒙石灰岩的储层性质，第2部分：渗漏和压裂的影响

为了了解成岩作用变化和结构变形对储层物性空间分布的影响，在法国东南部的研究区内，对微孔和致密的Urgonian（巴里米亚-阿普提安）石灰岩进行了综合的沉积学，成岩作用和结构分析。建立了碳酸盐岩的成岩史，并将其划分为与区域地球动力学活动事件相对应的阶段。岩相（光学，SEM和阴极发光显微镜），结构和地球化学（δ ¹⁸ O，δ ¹³ C）的研究进行了在碳酸酯，尤其是微晶和块状方解石表征水泥相，并调查它们与压裂发作关系。
