Description

Technical Field

[0001] The present invention belongs to the fields of virtual reality and carbon dioxide sequestration engineering, and particularly relates to a learning and display system for a carbon dioxide geological sequestration platform based on VR technology. Background Art

[0002] Most of the carbon dioxide sequestration platforms in China are located in deep sea waters far from the land, lacking convenient transportation facilities to communicate with them. The sequestration platforms are also affected by extreme climates and natural disasters. In most cases, engineering technicians and learning and research personnel cannot visit the site in person during critical periods to understand on-site problems, resulting in limited actual sequestration efficiency. In addition, during the actual operation of the platform, it is necessary to constantly monitor the carbon dioxide flow conditions in the wellbore (such as blockage conditions, gas-water ratio, etc.) and the physical properties of carbon dioxide in the sequestration formation, with a focus on the characteristics of temperature, pressure, and gas concentration changes over time. However, the engineering information is fragmented and scattered in multiple instrument devices, hindering technicians from efficiently retrieving and obtaining information. On the other hand, the carbon dioxide leakage problem during the wellbore injection process and the change in carbon dioxide concentration in seawater are also of concern, but there is currently a lack of a remote system to intuitively understand the carbon dioxide concentration distribution in seawater. Summary of the Invention

[0003] There is an urgent need for a convenient visualization display system that can, without the need to visit the site, efficiently observe the characteristics of the temperature, pressure, and gas concentration of the injected carbon dioxide changing over time and real-time monitor the change in carbon dioxide concentration in seawater. Therefore, a virtual platform for carbon dioxide geological sequestration that simulates the engineering site environment based on VR technology has reference value for promoting the development of unconventional oil and gas resources and learning and research in the field of carbon sequestration, and also provides a basis for subsequent real-time interactive tools developed based on VR technology.

[0004] To make up for this lack in this field, the present invention provides a learning and display system for a carbon dioxide geological sequestration platform based on VR technology, and proposes a development technical solution for the learning and display system in the carbon dioxide sequestration field.

5. A method for learning and displaying a carbon dioxide geological storage platform based on VR technology according to claim 1, characterized in that, Step 4 specifically includes the following sub-steps: Step 4.1: Construct the surface material of the virtual storage platform, the surface material of the simulated storage site, the rock layer noise material, the ocean current decal material and the post-processing material, the semi-transparent material of the sea surface, and the corresponding instances of each material, and apply the material instances to each object: the surface material of the virtual storage platform is applied to the platform, the surface material of the simulated storage site and the rock layer noise material are applied to the site, the ocean current decal material and the post-processing material are applied to deep-sea visualization, and the semi-transparent material of the sea surface is applied to the sea-level visualization effect. Step 4.2, conduct a trial run of the virtual sealing platform, and adjust the visualization effect according to the degree of performance occupation of the system on the device: limit the visual distance of the semi-transparent effect between the deep sea and the sea surface, limit the rendering accuracy, export the texture map to Substance Designer to modify the resolution and compress the texture map information within a limited number of channels.
