Appraisal of the volumes of fluid in a carbonate reservoir will typically require a reliable predictive model. This can be achieved by combining studies of well‐exposed carbonate successions with 3D models in order to obtain reliable quantitative data. In this paper, we present a detailed outcrop study and a 3D porosity model of a well‐exposed Oligocene carbonate ramp (Salento Peninsula, southern Italy) to investigate the nature of small‐scale facies and porosity heterogeneities. Porosity and permeability in the ramp carbonates appear to be controlled by the original mineralogy of skeletal components and by depositional textures. The aims of the study were therefore to identify the factors controlling porosity development in an undeformed carbonate ramp; to model the scale‐dependent heterogeneities characteristic of the facies associations; and finally to produce a 3D model of the porosity distribution.

意大利南部萨伦托半岛的渐新统（上CH石）碳酸盐岩中的相异质性和3D孔隙度建模

碳酸盐岩储层中流体体积的评估通常需要可靠的预测模型。这可以通过将暴露良好的碳酸盐演替研究与3D模型相结合来获得可靠的定量数据来实现。在本文中，我们提出了详细的露头研究和暴露良好的渐新世碳酸盐岩斜坡（意大利南部萨伦托半岛）的3D孔隙度模型，以研究小规模相和孔隙非均质性的性质。斜坡碳酸盐岩中的孔隙度和渗透率似乎受骨骼成分的原始矿物学和沉积质地的控制。因此，研究的目的是确定控制未变形碳酸盐岩坡道孔隙度发展的因素。建模相关联的尺度依赖的异质性特征;
