基于VisPy的油藏蒸汽腔形态变化三维动画控制

Three-dimensional Animation Control of Reservoir Steam Cavity Morphologic Change Based on VisPy

作为国外一种成熟高效的稠油开发技术,蒸汽辅助重力泄油(SAGD)在国内的应用也日渐成熟。因此,开发SAGD软件以辅助实际开发有着重要的现实经济价值。而在设计与实现该软件的过程中,需要利用三维可视化技术来准确反映油藏蒸汽腔的形态变化。结合实际SAGD开发软件需求,以PyQT5为GUI开发工具,基于当前较为新颖的高性能三维动画库VisPy,讨论了蒸汽腔三维展示部分中动画控制功能模块的功能需求、技术选型、详细功能设计和实现过程,给出了测试实例和结果。该工作对其他类似系统中设计与实现三维动画控制方案有着较强的实际指导意义,同时对新兴起的Python 3D可视化库VisPy的使用有一定的借鉴作用。

As a mature and efficient heavy oil development technology abroad,Steam Assisted Gravity Drainage(SAGD)has been increasingly applied in China.Therefore,the development of SAGD software to assist the actual development has important real economic value.However,in the process of the software implementation,it is necessary to use the three-dimensional(3D)visualization technology to accurately reflect the morphologic change of the reservoir steam cavity.Combined with actual SAGD software development requirements,PyQT5 was used as GUI development tool,and based on VisPy,a current relatively new high performance 3D animation library,the functional requirements,technical selection,detailed functional design and implementation process of animation control function module in the steam cavity 3D display section were discussed,and test examples and results were given.The work has a strong practical guiding significance for the design and implementation of 3D animation control schemes in other similar systems,and also has a certain reference for the use of the newly emerging Python 3D visualization library VisPy.
