摘　　要：为研究喇嘛甸油田三元复合驱油试验区储层流动单元特征,指导区块高效开发,利用密井网条件下测井资料对研究区沉积微相进行识别、细分,分析砂体展布特征、岩性、物性特征及非均质性;通过多参数选择、聚类分析、判别分析等方法对目的层各井点流动单元类型进行划分,并对各流动单元岩性、物性、流动性、压汞曲线等特征进行研究.结果表明,试验区河道砂岩多以一、二、三类流动单元为主,其中SⅢ9-10层河道内流动单元呈条带状连续分布,SⅢ4-8层河道内夹层较发育,多为物性夹层,与上下流动单元呈突变接触,流动单元呈断续状分布.该成果可为试验区方案设计及措施调整提供依据.In order to study the SⅢ4-10 flow units' characteristics of NE experimental in Lamadian oilfield and to promote efficient development,this paper discriminates and subdivides the microfacies on basis of former study and logging information in close well spacing condition in the pilot site. It deals with sandbodies distributing feature,lithological characters,physical property and nonuniformity. By multi-resonance switch,cluster analysis and discriminatory analysis,we subdivided the subject reservoirs. Furthermore,we also deal with lithological characters,physical property,fluidity and intrusive mercury curves of the flow units. The result shows that the types of channel sandstones' flow units in pilot site are mainly Class 1,Class 2 and Class 3,and the flow units of the channel sandstones in SⅢ9-10 have high effects on water flooding distribute as stripped series; while those of channel sandstones in SⅢ4-8 have relatively worse flood effectiveness distribute as interrupted series. The result of the research will provide a scientific basis for schematic design and individualized project adjustment.
