摘要

预测剩余油气饱和度分布是高含水期油田研究的重要内容,也是评价二次采油或三次采油方案的重要依据。认为预测剩余油气饱和度分布的有效方法是:首先充分利用井点测试资料,采用先进的随机建模技术进行精细油藏描述,建立精细的多种可能的地质模型;然后对多种可能的地质模型进行精细的油藏模拟,并将模拟结果与实际观测资料进行比较,挑选出理想的地质模型;最后利用优选的地质模型通过水驱油流线模型数值模拟来预测剩余油气饱和度分布。应用实例表明,该方法在满足精度的条件下,运算速度明显加快,具有广阔的应用前景。

Abstract

The prediction of remaining oil saturatio n distribution is the most important research aspect during high water-bearing  periods. It determines the scheme of secondary oil recovery and tertiary oil rec overy evaluation. One of the effective method is to adopt stochastic simulation  for fine reservoir description and establish several fine geology models taking  full advantage well testing data. The appropriate model is selected by fine rese rvoir modeling and comparing its result and the actual data. Finally, the remain ing oil saturation distribution is predicted through numeric simulation using wa ter displacing oil streamline simulator. Examples indicate that this method can  be carried out rapidly with high precision, and can be widely applied.
