Research Of Collaboration Mode Of Drilling Well Control Virtual Simulation

Well control is one of the most important links in the exploration and developmentprocess of oil and gas. The link has received a higher attention of leaders all the time,especially in recently years. With the continuous extension of oil exploration anddevelopment field, oil wells of different types appear continuously, such as oilfield deep wells,ultra-deep wells, horizontal wells. They bring more and more pressure and challenges to wellcontrol. It is difficult to guarantee the safety of well control work, at the same time, theproblem of "Shallow gas" lead to well control more difficult, only understand the grimsituation of well control fully, achieve the work of well control diligent, improve the wellcontrol skills effectively, can we realize the safety work of well control essentially. Therefore,well control training is very important.The operation of well control is very complex and there are many restrictions to on-sitetraining. The training effect is often far away from the desired effect, with the computersimulation technology development constantly, especially the development of collaborativevirtual reality technology, it makes the thing that the users in different locations at the sametime can play their characteristics of his role in the scene become a trend, the effect of wellcontrol training can be improved significantly with the introduction of virtual simulationtechnology.This thesis took virtual simulation to simulate cooperation process of the drilling wellcontrol, and received satisfactory result. Firstly, according to the characteristics ofcollaborative virtual environment, in this thesis, the drilling works are replaced by the virtualhuman joints, and the multi-user shared virtual environment based on network is used in theconstruction of virtual environment. It make people who locate in different positions caninteract with others through controlling their virtual human, to achieve the purpose ofsimulation training. Secondly, four kinds of Agent collaboration modes are concluded throughanalyzing all the collaboration relationships between people in the society, they are one to onemode, workflow mode, the share mode and mix mode, some of these modes are used in wellcontrol simulation system by writer, and the reality of simulation system is improved largely.
