【摘要】 来自油气藏的烃类物质的微渗漏扩散是普遍存在的。这里主要进行油气微渗漏扩散,在计算机上的物理实验再现过程和三维数值模拟。首先把实验提供的稀疏的数据,通过Kriging插值算法计算,得到三维重建中所需具有规则、分布均匀特点的数据,所得效果较好,并且算法编写简单、容易理解。其次,建立一种关于油气微渗漏扩散的三维数学模型,进行数值模拟,较好地仿真了演示油气微渗漏随时间扩散的过程。最后,简单地探讨了虚拟现实建模语言(VRML)在三维可视化中的运用。更多还原

【Abstract】 In the reservoirs,the phenomenon of the micro seepage is widespread.This paper mainly carries out a reconstruction and a numerical simulation of the oil and gas micro seepage proliferation of physics experiments on the computer.First of all,Kriging algorithm is used as the 3D interpolation method to convert the insufficient and random-arrayed data set provided by the experiments into sufficient grid data set which the three-dimensional reconstruction needs.Secondly,a three-dimensional mathematical model for simulating the micro seepage proliferation process is described.And the numerical results are compared with the reconstruction results.The comparison and the analysis indicate that this model is fairly effective.Finally,the Virtual Reality Modeling Language(VRML)is simply used in the three-dimensional visualization of oil and gas micro seepage proliferation.更多还原
