The Research And Realization Of The Training System Of The Oil Field Operation Under The Virtual Environment

Due to definite danger in the oil field work operation, it is difficult for the oil enterprisesto directly train the trainees in the oil field training on spot, especially in the emergencytreatment. The virtual simulation training system has the characteristics of excellent safety,extraordinary interaction and repeated drilling, therefore during the practical training of the oilfield work, excellent training effect can be obtained by using the virtual simulation trainingsystem for the training of relevant operation.This article devises and develops the training system of oil field operation under thevirtual environment, and does researches into the guidance theory and key technologyrelevant to its development.Elaborate the research background and research content of the subject, introducing theapplication of the virtual reality technique in the educational training, the development of thevirtual camera motion planning, the adult learning theories, constructivism theories,behaviorism theories, cognitivism theories, humanistic theories and selective attention, etc;Analyze the emergency operation process of the flowing well control. Devise thesystemic function modules, and device the free well site roam mode, enclosed illustrationmode, guide wizard operation mode, and open type free operation mode under the guidance ofthe bahaviourism;Analyze the working manner and operational approach of the real video camera, and setup the virtual camera mode in the virtual simulation scene. On basis of the selective attentionidea, the camera site of the virtual camera is adjusted by way of squared up in the imagecomposition, making the imaging pictures of the virtual camera, namely the training pictureson the screen, strengthen and highlight the concrete operations of the currently shotequipment, which can strengthen the memory of the trainees;On basis of the octree structure, preprocess the virtual scene by making use of collisiondetection. Plan the motion route of the virtual camera by making use of the route planningalgorithm according to the operation purpose of the users and dispose the route forsmoothness optimization, making the interactive animation steady and smooth during theinteraction between the trainees and the simulation system in order th help the traineesobserve and study the training contents.
