摘　　要：通过对各种地质、测井、测试以及开发动态资料等的研究 ,认为港东开发区注水后储层结构的变化是 :1孔隙度和渗透率普遍提高 ;2溶蚀粒间孔增多 ;3孔喉直径增大 ,孔喉比增大 ,微观非均质性增强 ;4粘土矿物总量减小 ,其中高岭石的相对含量明显降低 ;5储层亲水性增强 ;6储层层内非均质性和层间非均质性普遍增强 ;7少部分注水井有所污染 ;8储层出砂现象严重。并阐明了其变化的主要原因 。After waterfooding,changes of reservoir structure and heterogeneity in Gangdong development area are recognized thoroughly by studying the data of geology,well logging,testing and production performance From the aspects of basic characteristics of the reservoir,the physical and chemical action of injected water with formation and formation fluid as well as condition changes of formation temperature and pressure,the mechanism of reservoir changes are analyzed,the main reason of the changes is described and suggestions are made to solve the production problems of the area
