项目摘要

The overall objective of the proposed project is the development of numerical modeling capabilities for the simulation of processes during microbially enhanced coal-bed methane (MECBM) production and its implementation into the open-source numerical simulator Dumux (www.dumux.org). By supporting and supplementing experimental work, this model is then aimed at testing different hypotheses concerning the details of the reactive transport during MECBM processes which are still poorly understood. This can be achieved by means of comparisons between simulations and experiments at the Center for Biofilm Engineering at the Montana State University in Bozeman/USA (MSU-CBS) on a column scale and performing sensitivity analyses to determine the influence of various parameters. Where necessary, the model equations can be adapted according to new data and findings from the validation attempts with experimental data. It is envisioned that the newly developed model will become a key tool for ultimately transferring the knowledge from the laboratory scale to field-scale relevance and for designing scenarios to test the MECBM technology in the field. The numerical model will be essential in the further development of MECBM production technologies, in specific in the design of the planned MECBM field demonstration by MSU-CBE in collaboration with the United States Geological Survey (USGS).In summary, the expected outcome from the proposed project will be improved fundamental knowledge about MECBM processes achieved with a simulation tool in combination with experimental studies on the lab- and field-scale. The development of simulation capabilities is in no way aimed at reducing the importance of experiments, but it will decisively aid in focusing available time and effort on the key experimental studies and field setups.

拟议项目的总体目标是开发数值建模能力，用于模拟微生物强化煤层气（MECBM）生产过程及其在开源数值模拟器Dumux（www.dumux.org）中的实施。通过支持和补充实验工作，该模型的目的是在测试不同的假设有关的细节反应性运输过程中，仍然知之甚少的MECBM过程。这可以通过在美国博兹曼的蒙大拿州立大学生物膜工程中心（MSU-CBS）的模拟和实验之间进行柱规模的比较并进行灵敏度分析以确定各种参数的影响来实现。在必要时，模型方程可以根据新的数据和实验数据验证尝试的结果进行调整。据设想，新开发的模型将成为一个关键的工具，最终从实验室规模的知识转移到现场规模的相关性和设计方案，以测试在现场的MECBM技术。该数值模型将在MECBM生产技术的进一步发展中至关重要，特别是在MSU-CBE与美国地质调查局（USGS）合作设计计划的MECBM现场演示中。所提出的项目的预期成果将是通过模拟工具结合实验室和现场的实验研究，提高对MECBM过程的基本认识，规模模拟能力的发展决不是为了降低实验的重要性，但它将决定性地帮助把可用的时间和精力集中在关键的实验研究和现场设置上。
