使用含水影响增量判断油田含水上升的新方法

在分析油田产液量构成和含水变化的基础上,运用系统工程基本原理,提出一个新概念即油田含水影响增量,并推导出计算方法。实例计算分析表明,该方法能定量计算出单元的产液量和产水量对油田含水变化的影响,为系统评价含水变化、合理控制含水上升提供依据。

New method to judge water cut rising by using water cut influence increment

Based on the analysis of oil liquid production and water cut change, applying the system engineering principle, a new concept the water cut influence increment, is put forward to derive the calculating method. Example calculation shows that, this method can quantitatively calculate how the unit liquid production and water production influence the water cut change, which provide the basis for controlling water cut rising rationally.
