一、问题的提出注水开发油田的动态分析,就是油层内油水运动的动态分析。整个动态分析工作要回答的核心问题,我们认为有三个:第一,注入水是怎样运动的;第二,注入水在一定阶段上的分布状况怎样;第三,进一步挖潜的主攻方向是什么。以往的动态分析工作,主要是根据井口资料,各种测试资料,用统计办法来估计剩余储量分布。由于不能给出定量化的油水分布,大大地影响了动态分析任务的完成。这就要求我们研究一种有效的计算油层内油水饱和度分布的科学方法,为油田动态分析工作提供可靠的手段。
First, the issue put forward Waterflooding oilfield dynamic analysis, is the dynamic analysis of oil and water movement within the reservoir. We think there are three core questions to be answered in the whole dynamic analysis: first, how water is injected into water; second, what is the distribution of water infused at a certain stage; and third, what is the main direction for further potential exploration. The previous dynamic analysis mainly used the statistical methods to estimate the distribution of remaining reserves based on wellhead data and various test data. Due to the inability to give a quantitative distribution of oil and water, the completion of a dynamic analysis task has been greatly affected. This requires us to study an effective method for calculating the distribution of oil and water saturation in the reservoir and provide a reliable means for the dynamic analysis of the oilfield.
