| 摘 要： | 为了更好地描述低渗透多孔介质中的渗流规律,在实验的基础上,提出了随压力梯度变化的渗流能力修正因子,建立了描述低渗透多孔介质的非线性渗流模型,并将该模型应用于黑油模型模拟器中,初步模拟结果与现场数据符合的较好,计算结果表明在油水井附近压力梯度较大的区域,渗流能力修正因子值较大;在远离油水井连线区域,渗流能力修正因子值较小。

| Abstract: | In order to better describe the seepage law in low permeability porous media,the correction factor of percolation capability is presented which varies with the pressure gradient on the basis of experiment.A nonlinear seepage model is built which describes the low permeability porous media,and applied to the black oil model stimulator.The result of the preliminary simulation well conforms to the field data.The calculation result shows that the value of correction factor of percolation capability is larger in... |
