摘要
聚合物驱油是提高采收率的重要方法。但由于地层经过长期的注聚开发,储层物性发生了变化,加上油层发育的非均质性、存在高渗透带、大孔道等原因,形成泌124断块在注聚合物驱过程中存在聚合物沿优势渗流通道窜流问题,大大降低了聚合物驱油效率。为了快速识别优势窜流通道,建立了应用模糊综合评判方法优选优势窜流通道的数学模型,通过实例分析表明,运用综合评判方法优选优势窜流通道是一种客观有效的方法。该评价方法计算方便,易于操作和推广。
Polymer flooding is an important method of enhanced oil recovery,however,after long-term development of polymer injection,the reservoir physical properties has changed,and as the reason of the heterogeneity of reservoir development,exiting high permeability and large pore so on.The M124 fault block in the process of polymer flooding along the dominant path emerges channeling flow problem,it seriously restricted the development effect.In order to quickly identify the advantages of channeling the flow passage,the mathematic model is established for optimization advantage channeling circulation way by the fuzzy comprehensive evaluation method.By case analysis shows,using fuzzy comprehensive evaluation is an objective and effective method for optimization advantages of channeling the flow passage,which convenient calculation,easy to operate and promotion.
