项目摘要

Both Chinese and UK governments are committed to reducing emissions of greenhouse gases and have recognised carbon capture and storage (CCS) as an essential step towards this goal. The two countries have collaborated extensively and encourage new initiatives. This proposal is a response to the joint Call for Proposals from EPSRC and NSFC of China on CCS and will address a key fundamental issue under the priority theme 'Predicting and monitoring reservoir response' identified in the Call.Among the various CO2 storage options conceived, geological storage has achieved the best development, reaching a stage at which large deployments are foreseeable. There are three potential locations for geological storage, i.e. saline aquifers, depleted hydrocarbon reservoirs and un-mineable coal seams. The first of these is mostly favoured because it offers the greatest potential capabilities and is widely available. Over the past 10 years there have been over 10 saline aquifers injection operations conducted worldwide, and many more are being planned.A vast amount of work has been conducted recently studying a wide range of topics of CCS, from site section, environmental impact, public perception, economic viability, to technicality of injections and reservoir behaviours. In contrast, there are very limited studies addressing the underlying fundamentals of the trapping mechanisms and the multi-phase flow processes in porous media under complex thermodynamic conditions. The reason is that local measurement of flow in porous media at high pressure and elevated temperature is extremely difficult, and also there are no well-developed and efficient computational schemes for resolving two-phase flow in a large domain of complex geometries of porous media. The proposed research will make use of the latest development in measurement technology such as Magnetic Resonance Imaging (MRI) and numerical methods including for example Lattice Boltzmann Method (LBM). Detailed investigation will generate the much needed quantitative description of CO2 migration in porous media at extreme conditions relevant to saline aquifers encountered in carbon sequestration. and hence improve our understanding of the underlying physical processes. Experimental investigations on flow behaviour will be conducted at Tsinghua using a purposely-built supercritical CO2 test facility operating at conditions typical of deep saline aquifers with online measurement using a custom-built MRI. Both porous media made of sintered glass beads of constant diameter and real rock samples will be studied. Further experiments will be conducted at Leeds studying the geochemistry behaviours of the reactions of these rocks, as well as alternative reservoir lithologies and formation water chemistries. The computational studies will be led by Aberdeen and conducted at three levels: i) a finite-element solver of the fundamental equations governing the basic flow phenomena will be developed based on first principles. ii) An efficient two-phase flow LBM model for application of modelling CO2 migration in brine will be developed. It will be optimised for the particular fluid properties and thermodynamic conditions. Both of the above solvers will then be used to study the physical problems and generate further detailed information which is not available from experiments. iii) Exercises using CFD simulations with commercial software will also be continued. They will produce complementary data to compare with our new methods. Finally theoretical studies making use of the new results will be carried out by the whole multidisciplinary team. All experimental and computational results will be further processed to produce correlations/relationships for use with large scale simulations and will be studied comprehensively to develop further fundamental understanding of the phenomena of CO2/brine two-phase flow in porous media.

中英两国政府都致力于减少温室气体排放，并认识到碳捕集与封存（CCS）是实现这一目标的重要一步。两国开展了广泛合作，并鼓励新的倡议。本提案是对EPSRC和中国国家自然科学基金委员会CCS联合提案征集的回应，将解决“预测和监测水库响应”这一优先主题下的关键基础问题。在设想的各种二氧化碳储存方案中，地质储存取得了最好的发展，达到了可以预见的大规模部署的阶段。有三个潜在的地质储存地点，即含盐含水层、枯竭的碳氢化合物储层和不可开采的煤层。第一种方法最受欢迎，因为它提供了最大的潜在功能，并且可以广泛使用。在过去的10年里，全世界已经进行了10多次盐水注入作业，并且正在计划进行更多的作业。最近，人们开展了大量的工作，研究CCS的广泛主题，从现场剖面、环境影响、公众认知、经济可行性，到注入技术和油藏行为。相比之下，对于复杂热力学条件下多孔介质中捕获机制和多相流过程的基本原理的研究非常有限。原因在于高压高温下多孔介质内部流动的局部测量是极其困难的，而且在多孔介质复杂几何形状的大范围内，还没有成熟有效的求解两相流动的计算方案。拟议的研究将利用最新发展的测量技术，如磁共振成像（MRI）和数值方法，如晶格玻尔兹曼方法（LBM）。详细的调查将产生非常需要的多孔介质中二氧化碳迁移的定量描述，在与碳固存中遇到的盐水含水层相关的极端条件下。从而提高我们对潜在物理过程的理解。流动特性的实验研究将在清华大学进行，使用专门建造的超临界二氧化碳测试设备，在典型的深盐水含水层条件下运行，并使用定制的MRI进行在线测量。本文将研究恒径烧结玻璃微珠制成的多孔介质和真实岩石样品。进一步的实验将在利兹进行，研究这些岩石反应的地球化学行为，以及替代油藏岩性和地层水化学。计算研究将由阿伯丁领导，并在三个层面上进行：i)控制基本流动现象的基本方程的有限元求解器将基于第一性原理开发。ii)开发一种用于模拟盐水中CO2迁移的高效两相流LBM模型。它将针对特定的流体性质和热力学条件进行优化。然后，上述两个求解器将用于研究物理问题，并产生无法从实验中获得的进一步详细信息。iii)还将继续使用商业软件进行CFD模拟练习。他们将提供补充数据与我们的新方法进行比较。最后，利用新结果的理论研究将由整个多学科团队进行。所有实验和计算结果将进一步处理，以产生用于大规模模拟的相关性/关系，并将进行全面研究，以进一步了解多孔介质中CO2/盐水两相流动现象。
