含水率和含水上升率是评价油田开发效果和预测开发指标的核心指标,以含水上升率的定义演变出含水率变化分析方法,并从油田分不同的构成上看,不同组成部分的产液量和产水量都是变化的,对油田的总的含水率存在影响。由含水率的表达式出发,利用数学偏微分的方法推导出了从各个构成分量由于产液量和产水量的变化使总体含水率上升值。该方法可以从宏观上找到对总体综合含水影响最大的构成部分,为下一步调整措施的实施提供指导依据。
Moisture content and rising rate of water is the core index for evaluating the development effect and prediction of oilfield development. The definition of moisture rise rate evolves the analysis method of moisture content change. According to the different composition of oilfields, the production volume of different components And the amount of water produced vary, affecting the overall moisture content of the field. Starting from the expression of moisture content, the method of partial derivative of mathematics was used to derive the value of the increase of the overall moisture content from the change of the amount of liquid produced and the amount of water produced. The method can find the components that have the greatest impact on the overall integrated water content from the macro perspective and provide the basis for the implementation of the adjustment measures in the next step.
