Intelligent well completion technology is a new technology of digital and intelligent of the reservoir, whose core is the measurement and control system. The hardware system and software system of the measurement and control system of intelligent well completion are designed. The data of temperature and pressure are collected by the underground temperature and pressure sensors, the flow of each layer underground is calculated by using formula of temperature, pressure and flow, and a set of intelligent optimization of mining system is developed, therefore the mine production data can be monitored and analyed real-time. By using the reservoir exploitation theory, the optimal mining plan is determined for automatic control the flow control valves for each reservoir, and the exploitation of oil wells is optimized. Field test shows that the measurement and control system of intelligent well comnletion can realize the intelligent production of oil wells.
