This paper deeply researches the virtual simulation technology of oil gas gathering transferring system in the view of the present problem and defects existing in the virtual simulation technology. It treats oil gas gathering and transferring system in oil companies as main research object. The system extracts multiple eigenvalues of gathering and transferring tools' images which is on the basis of analysis experiment research in the image of oil gas gathering and transferring tools. This algorithm uses the HSV color space to extract images' color features and takes advantage of fourier descriptor to shape features. It identifies images by least squares SVM algorithm which finally implements real, safe, efficient training of staff, and has achieved good application affect after actual using.
