Abstract: In order to improve the overall appearance modeling and operator comfort of drilling rig, embody the styling orientation of the overall modeling of drilling rig “heavy and stable, simple and utility, beautiful and delicate”, and improve the user experience in security and ease operation, we introduce industrial modeling design into the design process of drilling rig. With the morphology, coating, and surface texture of the drilling rig being point-cuts, the formal beauty of overall appearance, the rationality of internal functional structure and the human-machine environment coordination of the rig has been highly integrated. Taking a series of ZDY directional drilling rig as the example, the specific application of industrial design to this type of new product development was presented in detail. The production and application of several drilling rigs show that the industrial design plays a very important role in improving both the overall appearance and operator comfort of the drilling rig.
