摘　　要：分析了影响新疆陆梁油田流动单元的基本因素及其相互关系,并基于流动单元的基本理论,运用了聚类分析和逐步判别分析相结合的方法,将研究区储层划分为4类流动单元,并利用非取心井流动单元判别模型对全区进行了流动单元划分。研究结果表明Ⅰ、Ⅱ类流动单元的物性和储集能力较好,主要分布在研究区东北部及中部偏西地区;流动单元的分布主要受控于微相砂体的分布;流动单元类型与油水分布关系密切。通过对流动单元的研究可以指导注采井网的部署,预测高产部位以及定性分析储量动用状况等。Because of its low porosity and permeability, Luliang Oilfield of Xinjiang is very difficult to develop. Therefore its internal structure and heterogeneity of the reservoir bed must be researched before the valid exploration is made. With the analysis of the basic influential factors about flow units and the interrelationship of all the factors, the reservoir bed in the oilfield is divided into 4 classes according to the basic theory of flow units and analysis techniques such as FZI and cluster analysis. Then the identification pattern of the flow units is established for the flow unit classification of the whole reservoir bed. The study reveals that the Ⅰ and Ⅱ flow units have good physical property and storage capability, most of which are distributed in the northeast the region of the study area. The distribution of flow units are mainly affected by microfacies of sand body. It is found that the classes of flow units and the distribution of juice are closely related to each other. It is suggested that the flow unit study will help dispose injection-production pattern, forecast the major high production bed and analyze the quality of the producing reserves.
