在油田注水开发过程中,由于各层系之间物性差异及同一层系非均质性的影响,致使在同一注水开发区内,有些采油井含水很低,而另一些采油井含水却很高。另一方面,随着含水率的不断上升,采油成本也必将不断增加。当含水上升到某一数值时,油井生产出的原油价值恰好抵偿油井生产过程中的全部劳动消耗。这个数值称为极限含水率。当含水率高于极限含水率时,油井生产必将出现亏损局面,油井应立即停止生产。因此,
In the process of oilfield waterflooding, due to the differences of physical properties and the heterogeneity of the same layer in different layers, some wells in the same waterflood development zone have low water content, while others have high water content . On the other hand, with the rising moisture content, the cost of oil extraction will also continue to increase. When the water rises to a certain value, the crude oil produced by the well just amounts to the full amount of labor consumed in the production of the well. This value is called the ultimate moisture content. When the moisture content is higher than the limit moisture content, oil wells will inevitably lose production, oil wells should immediately stop production. therefore,
