王场油田潜四段剩余油饱和度分布研究

STUDY OF DISTRIBUTION OF REMAINING OIL SATURATION IN THE FOURTH MEMBER OF QIANJIANG FORMATION IN WANGCHANG OIL FIELD

本文结合王场油田潜四段的地质及开发特点,提出综合开采动态、沉积环境和测井资料,研究剩余油饱和度分布的方法。通过分析计算,绘制出各主力油砂体的剩余油饱和度等值图及生产井的纵向剩余油分布曲线,总结了剩余油饱和度在平面及纵向上的分布规律,指出了油田挖潜调整的方向,经部分区块和少数井的调整实施,收到了较好的效果。

Based on the geological and development characteristics of the fourth member of qianjiang formation in wangchang oil field, in this paper, a method in which a great deal of field data such as production performance, sedimentary environment, well logging data and so on are used synthetically to study the distribution of remaining oil is proposed. After analysing and computing, saturation contours of the remaining oil in every main oil sand bodies and the vertical distribution of remaining oil in producing well are mapped. According to these data, the vertical and horizonatal distribution of the remaining oil saturation is presented. Resulted in the adjustment of the development program according to such a distribution map give confirmation of this method.
