Research on Virtual Simulation System of Marine Riserless Plugging and Abandoning Well Operation

As the operating environment and operating technology of marine riserless plugging and abandoning well are very complex, safety accidents extremely prone to occur. To solve the above problems, based on the system development framework, the virtual simulation system for marine riserless plugging and abandoning well operation is designed. The construction and refinement of the virtual model of equipment are completed by software such as SolidWorks. The Unity 3D virtual engine is used to realize the marine environment simulation, virtual scene roaming function, and monitoring interface design. It can monitor and control equipment status and operating parameters in real time. Furthermore, to integrate the mechanical model with the system, the Abaqus finite element software is used to analyze the coiled tubing. Finally, through case analysis, its application value in the study of marine riserless plugging and abandoning well operation is verified.
