论文摘要
我们提出了一个使用数字双技术的多孔介质中示踪剂传输的集成实验和模拟的框架。我们的设置中的物理资产是仪表尺度的流体钻机。数字双胞胎由传统的基于物理的远期仿真工具和一种校正技术组成，该工具弥补了模拟结果和观察之间的不匹配。后者增加了基于物理的模拟的范围，并使我们能够以定量的意义弥合模拟和实验之间的差距。我们描述了物理和数字双胞胎的设置，包括使用云技术的数据传输协议。数字双胞胎的准确性是在人为地扩散的案例中证明的，必须通过校正方法以及通过地质复杂介质中的模拟来补偿数字双胞胎的准确性。然后，通过操纵实验钻机中的流体注入和生产来将数字双胞胎用于控制示踪剂传输，从而实现了物理和数字双胞胎之间的双向耦合。
We present a framework for integrated experiments and simulations of tracer transport in heterogeneous porous media using digital twin technology. The physical asset in our setup is a meter-scale FluidFlower rig. The digital twin consists of a traditional physics-based forward simulation tool and a correction technique which compensates for mismatches between simulation results and observations. The latter augments the range of the physics-based simulation and allows us to bridge the gap between simulation and experiments in a quantitative sense. We describe the setup of the physical and digital twin, including data transfer protocols using cloud technology. The accuracy of the digital twin is demonstrated on a case with artificially high diffusion that must be compensated by the correction approach, as well as by simulations in geologically complex media. The digital twin is then applied to control tracer transport by manipulating fluid injection and production in the experimental rig, thereby enabling two-way coupling between the physical and digital twins.
