| 摘 要： | 利用油藏数值模拟方法对辽河油田冷41断块稠油底水油藏水平井水平段位置的优选进行了研究,分析了水平渗透率、垂直渗透率与水平渗透率比值、原油的粘温关系、水体倍数及油层厚度变化对水平段位置的影响。根据不同方案的数值模拟研究结果,获得了水平井水平段距底水的无因次距离随着参数变化的图版以及拟合公式,利用这些图版和拟合公式就可以对此类稠油底水油藏的水平井水平段位置进行指导，为同类油田开发提供依据。

| Abstract: | The optimum position of horizontal section for heavy oil reservoir with bottom water of Leng-41 block in Liaohe oilfield by horizontal drilling process is studied by using the reservoir numerical simulation technique. The ratio between horizontal, vertical permeability and horizontal permeability, the viscosity-temperature relationship of the crude, the fraction multiple of the bottom water and the effect of varied pay-zone thickness on the horizontal section position are analyzed. The numerical simulation results from different cases show the dimensionless distance of the horizontal section position to the bottom water, obtaining the chart changing with other parameters and matching formulas. This method can be as a guide for the similar heavy oil field development. |
