不同含水阶段合理产液量预测的一种新方法
|
摘要
生产实践表明放大生产压差提液是已开发油田上产稳产的主要措施之一。为了研究不同含水阶段合理的产液量,在前人研究无因次采液指数的基础上提出了无因次采液强度的概念,并根据相渗曲线获得了不同含水阶段无因次采液强度的理论图版。应用表明无因次采液强度图版可以在生产压差难以获取的情况下用来预测油井不同含水阶段合理的产液量,以及确定生产压差的相对大小。
It is showed that the increasment of the differentid pressure for high liquid production rate of producing wells was one of the main techniques used to enhance oilfield production. In order to determine the reasonable liquid production rate at different water cut stages, we proposed the concept of dimensionless liquid production intensity based on the previous study of dimension less liquid production index, and obtained its theoretical plate according to relative permeability curves. The application showed that the plate of dimensionless liquid production intensity could be used to predict the reasonable liquid production rate and determine the relative values of differential pressure ratio of producing wells at different water cut stages without knowing the differential pressure.
