剩余油分布解释技术在胜利油区的应用

Application of remaining-oil distribution interpretationtechnique in Shengli oil fields.

在油藏开发过程中，剩余油分布是人们普遍关心的问题，胜利油区注水开发时，由于油藏层系多，岩性复杂，非均质严重，因此，层间、层内不同部位水淹程度差别较大，各口井或区块剩余油分布也是不同的。文中着重阐述单层层内、同一层在平面上、单井剖面剩余油分布以及绘制多井剩余油分布剖面。最后，得出了几点重要看法。特别指出，根据剩余油分布的实际情况，采取适当措施后，可进一步挖掘油藏潜力。

Remaining oil distribution is an important problem which people show solicitude for inthe course of oil reservoir development. In water injection development in Shengli oil fields,the waterflooding degrees at different positions of a reservoir and of different reservoirs arevery different from each other,and there are different remaining-oil distributions in verticaland lateral extents,because of multilayer reservoir, complicated lithology and severe nonuni-formity.This paper describes the remaining oil distributions in vertical and lateral extents ofa single reservoir, and in single-well section, it also sketches how to plot multi-well sectionwhere remaining-oil distributions are indicated clearly. In conclusion, this paper statesauthors’ some important views. It is particularly pointed out that remaining oil can be ex-ploited by taking proper measures according to real remaining oil distributions .
