摘要
油藏的非均质性和油水粘度的差异 ,使得水驱开发的油田中低渗透层动用程度较低 ,生产井过早水淹 .多轮次调剖技术是一项重要的稳油控水措施 .综合考虑了堵剂驱油过程中的物理特性 ,应用局部网格加密技术 ,建立了高含水期油藏多轮次调剖流体渗流模型 ,并给出了有效的数值解法 ,且求解过程中线性方程组系数矩阵的存储采用行索引稀疏存储方案 .算例结果表明 :油田在高含水开发后期 。
The heterogeneity of reservoir and the viscosity difference between oil and water make the oilfield that production wells submerged by water too early. Multi- round profile control is an important measure to stabilize oil production and control water cut. A mathematical model of multi- round profile control percolation flow through the reservoir of high water is established. The local mesh refinement model and an effective numerical solution are also provided. From the simulating solution of an example, the measure of multi-round profile control plays a relatively important role in controlling water cut and enhancing oil production.
