喇嘛甸油田北东区块流动单元研究

流动单元是近年来提出的一项综合应用技术，对确定高含水期剩余油分布规律，改善开发效果具有重要意义。本文综合地质、测井、岩心、化验分析等多种资料，在单砂体识别的基础上，通过多参数选择、聚类分析等方法将研究区目的层划分为三种流动单元类型，利用判别分析建立了流动单元的判别函数，能够准确划分各井点的流动单元，在此基础上，查明各流动单元的特征及分布规律，并结合实际分析了油田高含水期开采阶段，采用流动单元分析方法对剩余油挖潜的作用。

Flow Unit Research in Eastnorth Area of Lamadian oil field

Flow unit is a synthesis applied technology which was proposed in recent years, has the important meaning to determine the rule of remaining oil distribution and to improve the development effect of oil field during the high water stage. In this paper, with the datas integrated of geology, oil well logging, core sample, chemical examination analysis and so on, and on the foundation of single sand body distinguishes, the target reservoir was divided into three kind of flow unit types through methods of multi parameter choice and cluster analysis , then the flow unit criterion function was established using the discriminant analysis. The flow unit of well points were divided accurately. The characteristic and the distribution rule of each flowing unit was verified. The effect for remaining oil potential tapping through flow unit was analyzed combined with the present situation of oil field during the high water stage.
