| 摘 要： | 由于复杂地质条件的约束,油藏非均质性较强,水驱油过程中各渗流通道阻力差异大,流体容易沿渗流阻力小的高渗透率通道流动,这就造成储层波及范围小、动用程度低. 为了控制渗流场各渗流通道的阻力,尽可能使各渗流通道阻力相同,提出了多段塞等渗阻调控驱油方法. 根据质量传输流体力学、物质平衡原理和各级化学驱段塞特征建立了等渗阻调驱复杂渗流数学模型,简化后通过积分变换求出一维多层分析解. 结合实验验证和理论计算压力特征分析发现等渗阻调驱能够大幅扩大波及体积,降低含水率,动用低渗透层原油,从而大幅提高采收率. |

| Abstract: | The constraint of complex geological conditions and the high heterogeneity of oil reservoirs make filtration resistance vary greatly in the process of water flooding.Fluid tends to flow along high permeability formation with low resistance,leading to a smaller reservoir swept volume and a lower producing degree.In order to control the resistances of all channels in the seepage field to balance the resistances as much as possible,a new method of controllable displacement of equivalent filtration resistance w... |
| Keywords: | water flooding filtration resistance control displacement complex flow pressure distribution |
