厚层层内非灼质性严重,并在吸水、产液剖面上体现出差异性;层间砂体连通性较好,隔层发育稳定,层间渗透性差异明显。平面上E,f小层岩性变化导致较强的平面非均质性。垂向上砂体的韵律性
变化和夹层的发育易形成物性分隔油蔗导致的剩余油富集。关键词:储集层;非均质性;剩余油;阜三段;海安油田

Abstract: The reservoir heterogeneity has a big effect on oilfield water flooding and the distribution of remaining oil. Aceording to the well logging and profile testing data,the research was conducted from three aspects ( inner layer,interlayer and lateral heterogeneity) of 3"member of Funing Formation in the Yuanjia Block. The results show that, within the thicker slim layers (E,f j’ ,E,f ") developed different types of rhythmic characteristics,muddy and calcareous interbeds. This led to the serious in-layer heterogeneity and reflected the differences between liquid producing profile and water injection profile, The sand of interlayer has a good connectivity,stable inter layers and obvious interlayer permeability difference, In the plane, the lithologic changing of E, f §’ gives rise to the stronger areal hetero geneity. In vertical,physical property separate the reservoir can form the residual oil concentrates owing to the rhythm of sand body and the development of interlayers.

引言
储层非均性是指储层的“四性”在平面及垂向上的各向异性"),它控制着地层流体的渗流特征,决定着油田注水开发的效果,影响着油田高产稳产时间和最终采收率高低(2)。因此,储层的非均质性
研究对油田开发具有重要意义。近年来,国内外学者从不同角度提出了多种储层非均质性的划分方案[35],一般将储层非均质性分为宏观非均质性和微观非均质性。研究区海安油田袁家断块已基本形成了完善的反九点注采井网,随着注水开发进人中后期,“三大矛盾”日渐突出,单层突进、平面舌进等问
