Abstract: The 3D environment created by the Graphic program of Drilling Simulator makes simulation effects approach a real wellsite more, and OpenGL makes it possible to control realtime 3D cartoon. It can be used in the Oil Enterprises for professional Drilling training, and play an important role in applying Computer Graphic Technology to the production of 3D Drilling cartoon. A method for accessing and controlling the 3D machinery models of Drilling Simulator based on OpenGL is provided, and the methods of Hierarchical Model and Object Oriented Programming to improve the flexibility and scalability of the program is used. In this way, the whole scene and models can be controlled and changed much more easily. Also, the programming efficiency has been improved obviously. At the same time, the scence of 3D cartoon is established.
