| Petroleum is a kind of strategic resource, and that is high cost to prospect and to develop. New petroleum equipment is continually developed by some countries in the world by introducing into new technology to reduce the cost. Along with maturing in the modern production development condition, Virtual Prototype technology and Product Data Management technology improved new production's developing and designing, also reduce its duration to market, buildup the competitive capableness of company. Surrounding the topic of technology on Virtual Prototype(VP) and Product Data Management(PDM), this paper studies the relational theory and technology about the VP and PDM of the Top Drive Drilling System(TDS), then develops and carries out it. This thesis mainly includes: Firstly, introduced the VP character and change in its system structure, researched the system structure, integrated frame, modeling and key technology about the TDS.Secondly, analyzed character of parametrical technology, and then requirement for modeling in the system. Based on it, analyzing the software character of the VP and CAD, pointed out component model of the virtual prototype system about the TDS, researched the relationship between management system and database. From the application, introduced the underlying environment to build up database, researched the principle which design database, and the method of organizing information about the parts in the TDS, in the meantime, based on have studied the integrated information, put forward for the system structure about the PDM, and researched its functional model.Lastly, introduced the integrated project and fulfilling interface methods between the virtual modeling system, analysis system and PDM system, and the interface about the virtual modeling system.Through VC program language and database technology, illustrated the virtual modeling system in the Pro/E, and validated the affectivity of the system which studied in this thesis.
