摘要:
指出流体在超低渗透油藏中渗流偏离达西定律，符合非线性渗流规律，结合矿场实际和室内岩芯数据建立了大45区块地质模型，采用非线性渗流数值模拟软件进行数值模拟．结果显示，该软件对实际区块同样具有很好的稳定性，区块开发过程中压力梯度大部分位于非线性弯曲段，非线性渗流区域占主导地位，进一步验证了采用非线性数值模拟软件的可行性．相比传统评价方法，该研究增加了压力梯度场参数，对评估超低渗储层的有效动用有意义．
Abstract:
Fluid seepage in the super-low permeability reservoirs deviates from the Darcy’s law, instead conforming to the law of nonlinear seepage. In this paper, on the basis of practical field and laboratory experiment data, the geological model of Da 45 block is established and the numerical simulation is carried on in line with the model. As to the practical model, the nonlinear seepage numerical simulation software also has good stability during the calculation. The calculation results show that, most pressure gradient belongs to nonlinear types and the nonlinear seepage dominates in a large scale of formation, which further testifies to the accuracy and importance of the nonlinear seepage numerical simulation software. Compared to the conventional evaluation method, a new parameter of pressure gradient is included, which is of significance to the cognition and evaluation of effective driving degree for super-low permeability reservoirs.
