摘要(Abstract)：

针对一些油田小层地质储量不清, 小层累计采油量不清, 因而小层剩余潜力不清、盲目性挖潜, 进入高含水开发阶段、稳产难度更大的实际情况, 为了经济有效开发油田, 开展小层剩余油定量化分析方法研究。通过动静态结合系列技术处理, 把全区原始地质储量合理地匹配到每口新老油井的小层上, 又客观地预测单井小层累计采油量等等, 获得目前单井小层剩余地质储量、剩余可动油量、采出程度等开发指标, 确定小层可挖潜的空间, 同时对“非储量层”采出量进行预测, 了解油层的真正采出程度。经过以往压裂效果分析, 该方法可信度达73 5%。
In consideration of unclear OOIP of sub-divided oil layers in some oilfields, vague accumulative oil production of this kind of layers,and not understanding the remained potential which is tapped without a fixed purpose,especially that oil production becoming more and more difficult when entering high-water-cut development stage, stable quantitative analyzing method is engaged to effectively develop these layers. Through a series of techniques integrating static and dynamic data, the initial OOIP of the whole block is reasonably allocated among the sub-divided layers of both old wells and new wells,and the accumulative oil production of these layers is objectively predicted and so on. The development indexes such as current remained OOIP,residual mobile oil,recovery factor of sub-divided layers in each well etc. have been obtained, the tapped potential of sub-divided layers is also determined. At the same time, the oil production of “untabulated layer” is forecast as well,thus the real recovery factor of oil layers can be made clear.After previous fracturing effect analysis, the method credit can reach 73.5%. The above study results possess more important significance for tapping old oilfield potential, establishing reasonable water injection strategy and enhancing recoverable reserves.
