Abstract

An improved algorithm for modeling the dynamics of petroleum product lenses based on the planned filtration equations is presented. The Oilfem 2 program code, which implements the algorithm, is supplemented with a generator of nonorthogonal grids and the ability to create or import geofiltration models; the dependence between the pumping rate of the petroleum product lens and its thickness is taken into account. The improved program code is applied on a test task to eliminate oil contamination, which is a round lens of petroleum products. The solution we obtained is compared to the analytical solution found by the LDRM program. The results have good correspondence between the two solutions for two criteria: the change in the flow rate of pumping oil products and the change in the volume of free oil products over time.

从石油产品的角度模拟含水层的修复

摘要

提出了一种基于规划过滤方程的石油产品透镜动力学建模改进算法。实现该算法的 Oilfem 2 程序代码补充了非正交网格生成器以及创建或导入地理过滤模型的能力；考虑了石油产品透镜的泵送速率与其厚度之间的依赖性。改进后的程序代码应用于消除油污染的测试任务，即石油产品的圆形透镜。我们获得的解与 LDRM 程序找到的解析解进行比较。结果在两个标准之间具有良好的对应关系：泵送油品的流量变化和游离油品体积随时间的变化。
