Development of Blowout Simulation Platform Based on Virtual Reality Technology
The training mode of blowout and fire rescue operation generally has the disadvantages of high risk of field simulation and slow accumulation of video teaching experience.It is necessary to develop a virtual reality(VR)training platform that is not limited by time and place.In the paper,we used unity3d engine to build a virtual well site environment,used particle surface rendering and particle system to simulate the effect of blowout and fire,established a multi-point source flame thermal radiation model,dynamically calculated the thermal radiation damage suffered by personnel,and delimited the safety range according to different thermal radiation damage levels.At the same time,the human-computer interaction and result event response of the rescue equipment were realized based on the layered composite collision body,and the integrated rescue process was completed.The results show that the safety distance should be more than 70m when the blowout is on fire;With the increase of flame inclination,the maximum safety dis-tance increases in varying degrees in the direction of flame tendency,and the minimum safety distance decreases in varying degrees in the opposite direction of flame tendency.The development and establishment of this platform has certain reference significance for safety rescue operations.
