摘要:
油气田开发中,水驱法仍然是最主要的开发方式,粗糙通道的存在对于两相流动的影响不可忽略.为研究油水两相在粗糙通道内的流动情况,采用直接求解纳维-斯托克斯(Navier-Stokes, N-S)方程的方法模拟两相流体在单一粗糙喉道中的驱替过程,采用相场法实时追踪两相界面.通过建立简单规则的粗糙通道模型,研究相对粗糙高度、水平粗糙单元间隙比和黏度比等因素对两相驱替速度及两相界面长度的影响.建立光滑通道模型作为对照实验,研究壁面粗糙性的存在对两相驱替的总体影响.最后建立复杂粗糙通道模型验证简单模型所得规律的正确性.研究结果表明,壁面粗糙性的存在将会大大增加两相流动阻力,从而促进指进现象的产生,使得驱替效率下降.
Abstract:
In the development of oil and gas fields, water flooding is still the most important development method. The influence of the existence of rough channel on two-phase flow cannot be ignored. To study the flow of oil-water two-phase in rough channel, the method of solving Navier-Stokes (N-S) equation directly is used to simulate the displacement process of two-phase fluid in a single rough channel, and the phase field method is used to trace the interface of two-phase fluid in real time. The effects of a series of factors, such as relative roughness height, horizontal roughness unit clearance ratio, viscosity ratio, and so on, on the displacement velocity and the length of two-phase interface are studied by establishing a simple and regular rough channel model. By establishing a smooth channel model as a control experiment, the overall effect of wall roughness on two-phase displacement is studied. Finally, the complex rough channel model is established to verify the correctness of the law obtained by the simple model. The results show that the existence of wall roughness will greatly increase the two-phase flow resistance, promote the occurrence of fingering problem, and reduce the displacement efficiency.
