Design of Digital Twin Architecture for Drilling Engineering

Digital twin is the process and method of forming a model of a production process in the physical world and its digital image in the digital world, which is the key technology for realizing the digital transformation of the petroleum industry. Based on the analysis of the current research situation of the digital twin technology in the drilling field of the oil industry, the overall architecture, data architecture and technical architecture of the digital twin technology in oil drilling are given, the key technologies such as the digital twinning technology in the drilling wellbore, the digital twinning technology in the geological environment, the digital twinning technology in the drilling rig, the dynamic process simulation in the downhole, and the real-time interaction of the physical-digital twinning technology are proposed, and the application scenarios of the digital twin technology in the pre-drilling business, the in-drilling business and the post-drilling business are analyzed. These results provide a technical reference for speeding up the practical applications of digital twin technology in drilling engineering and promoting the digital and intelligent transformation of drilling engineering.
