This article realizes data communication and real-time monitoring between well logging tem-perature controller and computer by using MSComm control component. The best PID parameters are de-termined by using critical ratio method and spot test and the best optimization control is achieved. It plays an important role to detect logging tools performance in simulating subsurface high temperature environ-ment, and to improve examining and repairing efficiency of logging tools. The program has been used to exam and repair kinds of logging tools.
