| 摘 要： | 采用先进的三维可视化物理模拟实验设备，全程跟踪了水平井开采非均质底水油藏时底水的脊进过程，研究了平面非均质底水油藏中水脊的形成与发展机理。研究结果表明，当水平井相邻井段的渗透率级差大于4时，处于低渗透区的水平井段对产能无贡献，渗透率级差对水平井的影响只是相邻井段间的影响，不存在非相邻井段之间的交叉影响，确定了非均质性严重的底水油藏中水平井产能低的真正原因。针对平面非均质油藏,提出了“先高后低、封高补低”的开发策略，并为挖潜剩余油指明方向。非均质底水油藏中底水脊进的过程为倾斜推进-高渗突破-油井见水-沿井扩展-次高突破-分段水淹。平面非均质性沿水平井三段式分布时，水平井的含水率为台阶式上升模式，且台阶数与连续分布的高渗透层段的个数一致。

| Abstract: | The present paper used an advanced 3-D visible physical model to observe the whole water cresting process in heterogeneous reservoirs with bottom water,and further investigated its formation and development mechanisms.The results indicated that a well section located in a low-permeability area had no contribution to deliverability when the permeability contrast of adjacent sections of a horizontal well was greater than 4,and horizontal wells were affected only by the permeability contrast of adjacent well s... |
