Research and development of intelligent oilfield software platform, covering intelligent reservoir, intelligent wellbore and intelligent well site three fields. Based on the three-layer cloud computing architecture design, VUE front-end separation, Springboot and micro-service distributed architecture are adopted, and digital twin 3D visualization and other technical means are adopted to realize the comprehensive perception and intelligent optimization of real-time display of information, real-time diagnosis of problems, real-time optimization of schemes and real-time analysis of effects of the oilfield surface - wellbore - reservoir.
