Constructing geocellular models of carbonate rocks using standard software is challenging since most of modelling packages are designed, first and foremost, to represent siliciclastic depositional systems, where rock properties are strongly facies-controlled. The distribution and components of carbonate depositional facies vary drastically across the geological timescale as a result of paleoclimate and its effects on carbonate-producing biota. Furthermore, reservoir architecture is less strongly controlled by depositional environment than in clastic settings, and rock physical properties, including fracture networks, are controlled by both primary components and their subsequent diagenetic alteration. This means that rock property distribution is less predictable than in siliciclastic systems, and less well represented by geocellular models that are designed to represent sedimentary architecture. In other words, in carbonate systems, the depositional and diagenetic history needs to be reconstructed in order to successfully model reservoir properties.

In this study a geocellular model was created by using a well-characterised outcrop analogue obtained from the Hammam Faraun Fault (HFF) Block, located on the eastern coast of the Gulf of Suez in Sinai, Egypt. This model integrates sedimentological, petrophysical, diagenetic, and structural information into a single database. The workflow utilizes the regional tectonic history, upscaled lithological logs, and two-stage facies modelling (reflecting in and ex situ depositional facies) and resulted in the creation a realistic model of remobilized carbonates that were deposited on the slope of a carbonate platform during a period of tectonic instability. Diagenetic overprinting was achieved using probability functions to reflect the history of burial, rifting, and the spatial relationship of stratabound and non-stratabound dolostone bodies. The study demonstrates a workflow for modelling mass-transport carbonate facies and multistage fault-related diagenesis so that flow controlling facies and diagenetically altered poroperm and fracture networks are accurately represented using commercially available modelling software, and in particular demonstrates how diagenetically controlled geobodies can be captured using simple algorithms.

使用标准软件构建碳酸盐岩石的地细胞模型是具有挑战性的，因为首先设计了大多数建模程序包，以代表硅质碎屑沉积系统，在该系统中，岩石的属性受到了严格的控制。由于古气候及其对生产碳酸盐的生物群的影响，碳酸盐沉积相的分布和组成在整个地质时间尺度上都发生了巨大变化。此外，与碎屑环境相比，沉积环境对储层构造的控制作用较弱，而包括裂缝网络在内的岩石物理性质均受主要组分及其随后的成岩作用控制。这意味着岩石属性分布比硅质碎屑系统更难预测，不太适合用旨在表示沉积构造的地细胞模型来表示。换句话说，在碳酸盐岩系统中，需要重建沉积和成岩史，以便成功地模拟储层性质。

在这项研究中，使用从埃及西奈苏伊士湾东海岸的Hammam Faraun断层（HFF）块获得的特征明确的露头类似物，创建了一个地细胞模型。该模型将沉积学，岩石物理，成岩作用和结构信息整合到一个数据库中。该工作流程利用了区域构造历史，高阶岩性测井和两阶段相模型（反射和异位沉积相），并创建了一个现实的固结碳酸盐模型，该模型在沉积过程中沉积在碳酸盐平台的斜坡上。构造不稳期。成岩叠印是使用概率函数实现的，以反映埋葬，裂谷的历史以及层积和非层积的白云岩体的空间关系。
