可动油饱和度偏低的(注水区域)。 Explanation: 两个相关概念: 1 油田注水 油田注水是一个石油类词汇,是利用注水井把水注入油层,以补充和保持油层压力的措施称为注水。 利用注水井把水注入油层,以补充和保持油层压力的措施称为注水。油田投入开发后,随着开采时间的增长,油层本身能量将不断地被消耗,致使油层压力不断地下降,地下原油大量脱气,粘度增加,油井产量大大减少,甚至会停喷停产,造成地下残留大量死油采不出来。为了弥补原油采出后所造成的地下亏空,保持或提高油层压力,实现油田高产稳产,并获得较高的采收率,必须对油田进行注水。 本句中的 injectivity / injection zones。前者为可注入能力,后者为注水区域。 2 可动油饱和度 可动油指的是在目前工艺前提下可采出的那一部分油。不可动油在目前工艺前提下无法采出。 可动油饱和度愈高,开发效果愈好。 Larger quantities of suspended oil may impair injectivity by reducing the permeability of the formation to water, especially in injection zones that initially have less than the mobile oil saturation. 本句大意: 大量悬浮油降低水油混合物的可渗透性,使其可注入能力受到削弱。在可动油饱和度偏低的注水区域,情况尤为严重。 |
