| 摘 要： | 底水脊进是制约底水油藏水平井开发效果的重要因素。为研究底水油藏水平井含水变化规律，综合 考虑6 种影响因素，基于详细理论研究与分析，用某实际油藏资料建立了底水油藏的数值模型，应用数值 模拟计算的累积产油量、累积产水量和累积产液量回归俞启泰水驱特征曲线，以求得反映水平井见水特 征的参数b。以参数b 为研究对象，具体采用响应曲面法研究不同因素对b 值的影响，以获得各影响因 素对水平井含水变化的影响规律以及影响顺序。研究结果对底水油藏的水平井开发具有理论及现场指 导意义。

| Abstract: | Bottom water coning is an important factor affecting reservoir development effect.In order to study the water cut change law of horizontal well in bottom water reservoir,based on theoretical study,numerical model for bottom water reservoir was established.Cumulative oil production,cumulative water production and cumulative liquid production were calculated to obtain the parameter b of Yuqitai water-drive curve.Then response surface method was used to study the influence of different factors on parameter b,and then obtain the influence law and order of the factors on water cut.The result has great significance for the development of horizontal wells in bottom water reservoir. |
