摘要
为研究油藏注水开发因层间非均质性所引起的堵塞规律,利用人造岩心模拟地下实际储层,结合油田生产实际,通过驱替不同水质的注入水驱替实验,研究了不同水质注水开发时在具有一定层间非均质性的储层的影响.结果表明,储层的渗透率在经过不同水质的注水开发后发生了相应的变化,其中具有一定的变化规律.该研究对储层层间非均质性强的油田的注水开发具有一定的指导意义.
Abstract
In order to study the blockage law caused by interlayer heterogeneity in reservoir waterflooding development,this paper uses artificial core to simulate the actual underground reservoir,combined with the actual production of oil field,through the injection water displacement experiment of different water quality,to study the influence of different water quality on the reservoir with certain interlayer heterogeneity during waterflooding development.The results show that the permeability of the reservoir changes after water injection with different water quality,and there is a certain law of change.This study has certain guiding significance for waterflood development of oil fields with strong interlayer heterogeneity.
