Multiphase & Multiphysics Modeling for Development of Low-Cost Flowmetering Solutions for the Oil & Gas industry

在高速多相流领域，目前的多相流模型难以实现对界面质量、动量和能量传递等小尺度特征和管道内不稳定段塞流等大尺度现象的多尺度预测。这在很大程度上阻碍了采用计算技术来理解多相流量计、分离器和控制装置。然而，油田部门的计算技术集成是自动化、以数据为中心的系统的重要组成部分，该系统适用于油田的生产优化，可以实现实时的逐井计量，目前只有不到5%的井进行了实时计量。本研究的目的是为涉及复杂多相流与几何非单调固体边界相互作用的问题的数值模拟开发先进的方法，并将其应用于与开发油田应用的下一代低成本流量测量解决方案相关的问题。然而，油田部门的计算技术集成是自动化、以数据为中心的系统的重要组成部分，该系统适用于油田的生产优化，可以实现实时的逐井计量，目前只有不到5%的井进行了实时计量。本研究的目的是为涉及复杂多相流与几何非单调固体边界相互作用的问题的数值模拟开发先进的方法，并将其应用于与开发油田应用的下一代低成本流量测量解决方案相关的问题。

In the field of high-speed multiphase flows, the multi-scale prediction of small-scale features such as interfacial mass, momentum and energy transfer and large-scale phenomena such as unstable slugging inside a pipeline, is notoriously difficult to achieve with the current generation of multiphase models. This has largely prevented the adoption of computational techniques in understanding multiphase flow meters, separators and control devices. However, the integration of computational techniques in the oilfield sector is an essential part of an automated, data-centric system suitable for production optimisation in the oilfield to enable real-time well-by-well metering, which is currently done on less than 5% of wells. The objective of this research is to develop advanced methodologies for the numerical simulation of problems involving complex multi-phase flows interacting with geometrically non-trivial solid boundaries and to apply them to problems related to the development of the next generation of low-cost flowmetering solutions for oilfield applications.
