accumulated inflow

To know the production status of the reservoir in water injected fields, we must take effective measures to improve our development level and provide reliable accumulated injected-water volume for reservoir description.

以渗流理论为基础 ,通过研究 ,建立了一种在无注水剖面资料的情况下用于小层累计吸水量劈分的方程 ,即动态劈分方程 ,并对涉及的各参数的取值方法进行研究。

By means of the real data of the polymer applied tracts of Sazhong oil field in Daqing, we also studied the relations among cumulative oil production, cumulative liquid production and cumulative water production in different coordinate systems and analyzed the characteristics of the displacement characteristic curve under polymer flooding.

在描述水驱特征曲线的基础上 ,推导出聚合物驱条件下驱替特征曲线的理论表达式 ,并应用大庆萨中油田聚合物工业化应用区块的实际资料 ,在不同坐标系下 ,研究了累积产油量、累积产液量、累积产水量之间的关系 ,并分析了聚合物驱替特征曲线的特点 。

Acording to the data from the experiment,we carried on a judgment to the loess water saturating process and obtained the rule of the moisture content at different depth,cumulated saturating moisture,velocity of saturating and water power gradient and so on changing with time.

根据实验所得数据资料,首先对黄土饱水过程是否完成进行了判断,然后对黄土层不同深度体积含水量、累积饱水量、饱水速率、不同深度处的水力梯度等随时间的变化规律进行分析。
