摘要
在油气集输工序培训系统设计的研究中,油气水三相分离设备是油气集输生产工序的重要组成部分。在分离过程中涉及到复杂的流场变化,传统方法利用物料平衡或能量守恒建立的静态模型不能满足高精度动态仿真的要求。针对上述问题,采用Stokes方程和Raoult定律分别对油滴分离程度和烃类气体析出程度进行计算,从而分别建立油气水三相数学模型,构成三相分离设备的动态仿真模型。以大庆油田某联合站为例对模型进行验证,结果表明仿真模型能够动态模拟分离过程中的工况变化。最后应用仿真模型支撑3D Max和Virtools软件开发的虚拟现实交互环境运行,实现了员工在虚拟现实场景中安全高效培训。结果表明实际使用取得了较好的应用效果。
The three- phase separation equipment for gas,water and oil is an important part in the oil and gas gathering and transferring production process. We used Navier - Stokes Equation and Raouh＇s Law to ealeulate the degree of oil separation and hydrocarbon gas separation respectively, established a mathematical model of oil and gas water three - phase separation equipment and constituted a dynamic simulation model of three - phase separation e- quipment. Taking the example of a Daqing oilfield combination station to verify this model, the results show that the model can dynamically simulate the changes in the process of separation. Finally, the mathematical model was used to support virtual reality interactive environment built by 3D MAX and Virtools, so to achieve the employees＇ safe and ef- ficient training and it has achieved good results according to the actual uses.
