| 摘 要： | 应用传统的对流扩散方程模拟聚驱后示踪剂产出曲线存在不适应性,将产生质量不守恒或模拟不出实际产出曲线问题.根据连续时间随机游走(CTRW)理论,利用CTRW模型对含聚合物的示踪剂测试实验的产出曲线进行模拟.结果表明:CTRW模型模拟的示踪剂产出曲线克服了基于传统的对流扩散方程模拟示踪剂产出曲线时所遇到的问题;CTRW模型对于模拟聚驱后示踪剂产出曲线具有良好的适应性,比传统的对流扩散方程模拟范围广.

| Abstract: | Using the traditional convection-diffusion equation to simulate the production curve of tracer after polymer flooding revealed significant inadaptability,This paper is based on the continuous time random walk(CTRW) theory and uses the model of CTRW to simulate the production curve of tracer test experiments containing polymer.The results show that this method overcomes the problem encountered in using the traditional convection-diffusion equation to simulate the production curve of tracer.CTRW model for simulation of the production curve of tracer after polymer flooding has a better adaptability and a wider range of simulation than the traditional convection-diffusion equation. |
