Since downhole operation training system can't meet the staff' requirements of learning whenever and wherever and training content lack of interactive, a set of multi-platform which supports 3D interaction of the downhole operation simulation training system is established. This system applies many technologies such as WEB, Navigation Mesh, Database, Android, fused mobility training, digital training, interactive training, optimizes the mode of tradition training, solves the problem of data source supporting in multi-platform, overwrites target homing road with the help of Navigation Mesh. Downhole operation training isn't restricted by network and equipment, interactive training content, and has the great value of improving training quality and reducing the accident rates of job location.
