Various key techniques of the chock system were elaborated, such as electric con trol system design based on CAN bus technology, mechanical structure design based on CAD/CAE, downhole temperature and pressure data collection and processing based on digital information technology and software design based on modular layering method. The con trol software and operation process of the practical system were tested and analyzed. The result demonstrated that the intelligent down hole throttle system has two main advantages of realtime monitoring and realtime remote control and throttling, which can provide e quipment supports for intelligent throttling technology. These methods have some reference for other researches in developments of intel ligent downhole tools.
