基于三维参数随机L系统的页岩压裂裂缝延展可视化
首发时间:2018-05-16
摘要:采用储层改造压裂技术进行油气开采,地下开采过程不可见。本文提出了一种基于三维参数随机L系统的裂缝生成算法,通过利用三维产生式规则定义裂缝的延展模式并利用海龟作图的方法实现了裂缝延展的三维动态可视化。实现了在拟三维压裂模型下裂缝可视化的三维建模,实现效果更接近于实际地层中的裂缝形态,增强了人们对三维裂缝形态及延展过程的认知。

Visualization of shale fracturing fractures based on three-dimensional parameter random L system
Abstract:The underground mining process is not visible using reservoir reconstruction fracturing technology for oil and gas exploitation. This paper proposes an algorithm of crack generation based on 3d parameter random L system , by using 3d production rules define the crack extension model and the method of using the turtle drawing for 3d dynamic visualization of crack extension. The results show that the algorithm can achieve a good visualization effect, which can effectively enhance the cognition of 3d fracture morphology and extended process.
Keywords: computer application visualization shale gas fracturing 3d L system.
