本文作者提出了一种工作流程，旨在最大限度地整合运营商碳捕获与封存 (CCS) 项目中的实验分析与建模活动。该工作流程能够将油气藏表征和管理方面积累的技能与二氧化碳捕获与封存的目标相结合。该集成工作流程采用跨学科方法开发，能够构建充足的数值模型，用于预测 CCS 期间的储层和盖层行为。
对岩心进行沉积学研究，以获得储层及其相关主盖层的沉积学模型。该研究包括沉积学岩心描述、储层复合体尺度的地震层位解释以及测井对比。考虑到与沉积环境相关的岩性变化，此步骤对于准确选择用于工作流程的储层和盖层的代表性样品至关重要。
岩芯表征。从储层和盖层采集的岩芯样本从矿物学、岩相学、岩石物理学和地质力学的角度进行表征。
In this work, the authors present a workflow developed to achieve maximum integration between experimental analytical and modeling activities in the operator’s carbon capture and storage (CCS) projects. The workflow allows integration of the skills developed in hydrocarbon reservoir characterization and management into the objective of capture and storage of CO2. The integrated workflow, developed with an interdisciplinary approach, permits adequate population of numerical models for the prediction of reservoir and caprock behavior during CCS.
A sedimentological study is performed on cores to obtain a sedimentological model of the reservoir and the related primary seal. This activity includes sedimentological core description, seismic-horizon interpretation at the storage-complex scale, and well-log correlation. Considering the variability of the lithologies related to the depositional environment, this step is necessary for an accurate selection of representative samples for both reservoir and caprock to be used in the workflow.
Plug Characterization. Plugs sampled from the reservoir and caprock are characterized from mineralogical, petrographic, petrophysical, and geomechanical points of view.
