Research And Implementation Of Oil Well Fracturing Simulation Training System

Virtual reality technology can provide a realistic and interactive 3D environments, research in all areas of its growing importance, and has made great progress. People realize that the combining the education and training with its, will bring a lot of advantage that traditional education and traning doesn’t have, this idea has ben unanimously endorsed by all areas of socity. Oil Well Fracturing job is cumbersome operaton, invisibility, much operating equipment, high-tech, harsh operationg environment, difficult and risk construction, easily lead to significant property damage and casualties.Therefore, Oilfield enterprises attach great importance to the training of fracturing technology, However, the traditional traning of fracturing is limited of space, time, number, especially underground operation can not feel in reality, Mostly through the accumulation of practical experience to complete, it is difficult for employees to achieve mastery of the knowledge of fracturing. The Virtual Training Technology and oilfield fracturing combined, providing staff with a realistic virtual fracturing environment, greatly enhance the professional skills of employees. But in order to achieve a more realistic simulation effect, the virtual system resource data will be very large, this creating a great burden for the dynamic rendering system, currently on how to achieve the optimization of large-scale scenes is still a hot and even a difficult applied research.This paper presents a simulation-based training system for oilfield fracturing, aims to truly restore the the fracturing site and the whole process of fracturing through this system. In order to solve the too large system caused by realistic effects, making it slow to load and the screen flashes and serious Caton phenomenon when run on a web page. This paper uses a improved scene optimization method based on LOD technique in virtools, which combines the LOD technology,scenes b lock and viewpoints related. Through experimental verification, Proved that the method is correct and effective. In the process of model optimization, we found the overall appearance of the model sometimes was destroyed, Therefore, In this paper, in-depth study of the progressive mesh algorithm and carried out experiments to solve the problem.In this paper, fracturing simulation training systems is full compliance with the fracturing process and operating procedures standard, provide a good interactive learning. Combing the LOD technology and scene blocking to optimize the system, to satisfy the running real-time rendering of complex scenes demand.
