基于采油速度和含水率的合理注水强度确定方法
method to determine the optimal water injection intensity based on oil production rate and water cut
注水是保持油层压力、改善油田开发效果的重要手段之一，而分层注水又是目前水驱油田的主要工艺。对于不同油层，如何做到"配得准"，是发挥各类油层作用的关键。本文提出了一种基于含水率和采油速度确定合理注水强度的方法。该方法基于实际层系井网参数，建立概念模型，进行数值模拟计算，得到注水强度与采油速度、含水率之间的关系图板，从而利用改图板确定不同含水阶段、不同采油速度条件下的合理注水强度。
Water injection is one of the important way for maintaining reservoir pressure and thus improve the oilfield development effect. Separate zone water injection is the main technology of water injection. For every kind of reservoir, optimal water intensity be allocated is very crucial for playing their role. This paper proposes a method to optimize the water injection intensity based on oil production rate and water cut. Conceptual model is constructed on the basis of real reservoir. By numerical simulation, a chart is derived which describes the relationship of water injection intensity versus oil production rate and water cut. Using this chart, we can determine the optimal water injection intensity for different oil production rate and water cut.
