摘　　要：注水开发的老油田在注水开发的中后期会出现含水率高、产油量低等问题,因此对于水驱优势通道的识别成为了中高含水阶段主要的研究目标。基于对前人文献的调研,发现识别优势通道的方法主要运用模糊综合分析法,了解优势通道形成的原因以及影响因素,其包括储层的强非均质性、注水强度、原油黏度、岩石骨架结构等因素。储层连通性评价是油田开发的重要研究内容,介绍了井间连通性的分析方法,并通过建立井间动态反演模型定量分析油藏井间连通性,运用Rdos模拟能够更准确地了解油藏井间连通性、识别优势通道,对油田开发具有很好的指导作用。The old oil fields developed by water injection are in the middle and late stage of water injection development,which will have the problems of high water cut and low oil production.Therefore,the identification of water drive dominant channels has become the main research goal at this stage.According to the previous literature research,main identifying method of dominant channels is the fuzzy comprehensive analysis method to analyze the dominant channel formation reasons and influencing factors,mainly including the strong heterogeneity of reservoir,water injection strength and viscosity of crude oil and rock skeleton structure and other factors.The reservoir connectivity evaluation is an important research content in oilfield development,some methods of interwell connectivity analysis were introduced,and through the establishment of interwell dynamic inversion model,quantitative analysis was carried out on the reservoir connectivity between wells,and Rdos simulation was used to more accurately understand the reservoir interwell connectivity,identify channel advantages,which has a good guiding role for oilfield development.
