摘要

中国东部油田长期注水开发

油藏高耗水条带发育

导致注水效率降低。为了明确高耗水条带发育的影响因素

以南阳双河北块为研究对象

分别分析了注入速度、渗透率级差、渗透率变异系数、地层系数四个因素对发育高耗水条带的影响

结合正交实验比较四个因素的影响因素相对大小。研究得出渗透率高、注入速度小、渗透率变异系数和渗透率级差高

更容易发育高耗水条带并导致水驱开发效果变差;在地层系数、注入量一定的情况下

渗透率高

更容易发育高耗水条带。通过正交试验

确定了渗透率变异系数对发育高耗水条带的影响最大

渗透率级差以及地层系数的影响次之

注入速度影响最小

为油田后期生产调整提供一定的参考。

Abstract

For the oilfields in east China with long-term water injection development

the water injection efficiency is gradually reduced due to the developed high water consumption strip in reservoir. In order to define the influence factors of development of the high water consumption strip

taking northern Shuanghe block in Nanyang as the research object

the influences of injection rate

permeability ratio

permeability variation coefficient and formation coefficient on the development of high water consumption strip have been analyzed respectively. Combined with orthogonal experiment

the relative influence level of the four factors is compared. The results show that high permeability

low injection rate

high permeability variation coefficient and high permeability ratio are more likely to cause the problems. With a certain formation coefficient and injection amount

high permeability is in major. Through the orthogonal test

the permeability variation coefficient influences most

followed by permeability ratio and formation coefficient

and the injection rate influences least. This study provides some reference for the adjustment in the later stage of oilfield production.
