| 摘 要： | 利用塔里木油田塔中4油田(TZ4)底水油藏相关的地质、流体数据建立数值模型。在所建模型的基础上,应用数值模拟计算的累积产油、产水和产液量回归俞启泰水驱特征曲线,以反映水平井见水特征的参数b。以参数b为研究对象,采用正交试验的方法研究不同因素对b值的影响,筛选影响水平井见水特征的主要因素,认为原油粘度、油层厚度、非均质性及水平井水平段在油藏中的位置是影响水平井含水上升趋势的主要指标。最后建立主要因素与b值的关系式,结合俞启泰曲线b值图版,提出预测水平井见水规律的公式——图版法(F-b法)。应用F-b法对塔里木水平井含水率进行预测,并与其他相关方法及实际生产数据对比,认为F-b法可作为预测塔里木油田水平井含水率、估算可采储量的一种有效方法。

| Abstract: | The geological and fluid property parameters of the TZA reservoir, a bottom water reservoir in the Tarim Oilfield, were used to set up a numerical model. The model was adopted to calculate the cumulative oil, water and fluid production, which were then used to regress the parameter b, disclosing the water cut rising performance, in the Yu Qitai Water Drive Curve. Orthogonal tests show that oil viscosity, reservoir thickness, heterogeneity, and the location of the horizontal section are the main controlling factors of water cut rising performance for horizontal wells. The relationship between these factors and the parameter b are established, and then the Formula to Plate method is presented, combining the Yu Qitai Plate of b, to predict the water cut rising performance. Application in the TZ4 reservoir demonstrates that the F-b method can be used to predict the water cut of horizontal wells in the bottom water reservoir. |
