摘要
底水油藏内部发育隔夹层,对油藏早期开发井起到延缓底水的作用,但开发后期,准确寻找剩余油富集区是一大难题,水平井呈现底水和边水双重驱动的特征,剩余油分散,实施调整井难度大。在结合动态资料和静态资料分析后,研究不同部位水平井的水淹模式、剩余油分布,打破原有思路,在底水油藏开发后期精准寻找剩余油,实施调整井。为油田后续高效开发提供了依据。
Interlayer developed in bottom water reservoir,it can delay the bottom water for the development wells of the reservoir,but at the later stage of development,finding the remaining oil enrichment area accurately is a difficult problem,the horizontal well is driven by bottom water and edge water,remaining oil is dispersed,It is difficult to implement adjustment wells。After the combination of dynamic and static data,study on waterflooding pattern and remaining oil distribution of horizontal wells in different parts,finding remaining oil in the later stage of bottom water reservoir development to implement。It provides the basis for the subsequent efficient development of oilfield.
