This paper introduces the virtual training and its superiority,discusses the key technologies of Oil Field Security Operation Simulation System,including 3D modeling,construct virtual visual channel,collision detection and so on,and particularly discusses the whole system realization from the model creating to the motion simulation.

Because the profiles of two-dimension Gabor base functions are similar to those of human visual cortical cell receptive field and the middle frequency of visual channels has octave relationship, a video watermarking algorithm is proposed based on spatio-temporal multi-channel model using 3D Gabor transform in this paper.
