五星庄油区剩余油分布及挖潜研究

Remaining Oil Distribution and Tapping the Potentialresearch in Wuxingzhuang Oildom

剩余油分布特征是油田开发需要解决的主要问题之一。文章应用矿场资料法半定量地描述了五星庄油区主力区长8、延9小层剩余油分布状态,对该块剩余油在油藏平面和纵向的分布特征进行了详细研究,并对剩余油分布类型提出了5种相应挖潜技术对策,为油田后期开发调整及剩余油挖潜提供了依据。

Remaining oil distribution feature is one of the major problems to be resolved in developing oilfield. In the paper, the method of field data is applied to describe the remaining oil distribution semiquantitatively in Yanchang 8 and Yan＇an 9 sublayers of main region in Wuxingzhuang oildom, and having a detail research about the distribution characters in the reservoir plane and longitudinal area of the remaining oil in this area, putting forward 5 types of technical countermeasures for tapping the potential according to the types of remaining oil distribution, which provid the basis for later oilfield exploration.
