Abstract:

In view of the inefficiency and high cost of current oil well management,administrators are not able to accurately know the on-site production status in real time,an automatic analysis intelligent oil well management system based on visual intelligent monitoring and neural network expert system is proposed. Compared with traditional oil well management system,intelligent oil well management system can realize real-time transmission of on-site production data,improving the real-time characteristic and authenticity of data. Real-time monitoring of oil well production site through intelligent camera device improves oil well production safety. When the on-site production fails,the system automatically recognizes it through the neural network expert system,intelligently opens and shuts in the well and informs the on-site personnel to dispose in time,improving the production efficiency. The system comprehensively perceives oilfield production performance and realizes visual intelligent monitoring of oilfields. The forecast of the trend of oil and gas fields continuously optimizes oil and gas field management. The intelligent oil well management system has been installed in more than 120 wells,the field application effect is good.

Key words: oil well management, visualization, intelligent monitoring, intelligent expert system
