注水利用率方法评价油藏开发效果

Appraisal on Development Effect Applying Injection Usage Factor

本文通过注水利用率方法对水驱砂岩油田进行水驱效果评价。以阶段存水率为基础,引入了无因次注入曲线和无因次采出曲线,回归出不同水驱采收率条件下,阶段存水率与采出程度关系式,并绘制成了二者关系标准图版,利用该图版可对开发调整效果进行评价。

In this article, the effect appraisal of water flooding is carried on through the method to usage factor of water injection in the sandstone oil field. Taking the stage water storage factor as the foundation, introducing the nondimensional injection curve and nondimensional production curve ,, the relationship between the stage water storage factor and recovery percent of reserves is obtained under the different water flooding recovery condition. Standard relations curves sversion are drown up, used this chart it is possible to carry on effect assessment of development and adjustment.
