Design And Implementation Of 3D Visualization Interactive System For Subsea Oil And Gas Production System

The underwater production system is the key to the development of deepwater oil and gas.Due to the long-term complex underwater environment and the characteristics of multi turning and multi diameter changing of the internal pipeline,the whole production process is often faced with contingency contradictions or sudden uncontrollable factors.Any mistakes in decision-making and operation may cause huge economic losses,especially the slug flow and hydrate generation in the production pipeline,which will have a huge impact on the entire system.Due to the invisibility inside the pipeline,it is difficult to observe the dynamics of the fluid.Therefore,it is of great significance to develop a three-dimensional visualization interactive system for underwater oil and gas production systems based on actual production data and the operation process of underwater oil and gas production systems,and to achieve the prediction and three-dimensional visualization simulation of plug flow hydrates in the pipeline of underwater oil and gas production systems.Firstly,the overall scheme design of 3D visualization interactive system for subsea oil and gas production system is carried out.In-depth analysis of the three-dimensional visualization interactive system requirements of subsea oil and gas production system,overall analysis of the system,to establish the development process;By comparing and analyzing common development platforms,the development platform is determined,and the overall architecture design of 3D visualization interactive system for subsea oil and gas production system is completed.Secondly,the design and test of 3D visual simulation module of subsea oil and gas production system are carried out.According to the overall layout scheme of deepwater subsea oil and gas production system in a gas field in South China Sea,a virtual scenario of subsea oil and gas production system under Marine environment is established.Based on the basic equation of fluid and the visualization method of fluid texture,the physical motion of fluid is rendered.By writing scripts,a simulation motion control module is developed to realize the interactive motion control of key valves.The design of 3D visual simulation module is completed,and the unit function test is carried out to verify the rationality and usability of the design of this module.Thirdly,the design and test of slug flow and hydrate prediction module in the pipeline of subsea oil and gas production system are carried out.The mathematical model of slug flow and hydrate prediction in the pipeline of underwater oil and gas production system is established and solved by programming.The design of the prediction module of slug flow and hydrate in the pipeline of underwater oil and gas production system is completed,and the functional test and real-time test are carried out to verify the rationality and effectiveness of the design of this module.Finally,the functional realization and test of 3D visualization interactive system of subsea oil and gas production system are carried out.The interface design and interface module development are carried out to realize real-time communication and interaction functions,and the system integration and testing are completed,which verified the function and rationality of the three-dimensional visualization interactive system of the subsea oil and gas production system.The system can provide immersive and realistic 3D scenes for managers and operators,and provide a safe,economical,reliable and effective training environment.It has important scientific significance and practical engineering application value for improving the availability of subsea oil and gas production system equipment and reducing risks and costs.
