| 摘 要： | 低渗透油藏中存在启动压力梯度,采用达西渗流已经无法准确描述油藏中流体的流动,为此提出了低渗透油藏启动压力梯度数学表征方法,建立了考虑启动压力梯度非线性渗流模型以及相应的数学数值模型,在现有数值模拟软件的基础上编制了非线性渗流数值模拟插件,并将其应用到油田模型中,计算表明,初步模拟结果与现场实际数据基本吻合,验证了方法的正确性。 |

| Abstract: | Low permeability reservoirs exists start-up pressure gradient. And Darcy law has been unable to accurately describe the reservoir fluid flow.The mathematical characterization of the start-up pressure gradient method was proposed in this paper in Low permeability reservoirs,and nonlinear flow model and the corresponding mathematical model and numerical model was built.Then nonlinear flow numerical simulation software based on the existing numerical simulation software has been developed.At last it was applied to a small oil field model.Calculations show that the initial simulation results are consistent with the actual data and verify the correctness of the method. |
| Keywords: | Low permeability reservoir Nonlinear flow Start-up pressure gradient Reservoir numerical simulation |
