摘    要:针对低渗透厚油层引入能有效表征优势窜流通道的4项参数,应用加权K-means聚类算法开展优势窜流通道的定量识别方法研究。利用该方法对乾安油田Ⅰ区Ⅶ砂组油藏59口井177小层进行识别,诊断出22口井存在优势窜流通道,与研究区示踪剂检测结果基本相符。根据优势窜流通道的单井识别结果,绘制了优势窜流通道平面分布图,研究其分布规律。优势窜流通道的分布区域主要受砂体微相、砂体形态及古水流方向的控制。

关 键 词:低渗透  厚油层  优势窜流通道  加权K—means聚类算法  定量识别  储集层  非均质性

Abstract:By taking a thick reservoir with low permeability as a case, a method was investigated to quantitatively identify the advanced channeling paths. The channeling paths was characterized by four types of parameters and then identified quantitatively by using K-means cluster algorithm. This approach was applied to 59 wells in sand formation Ⅶ Block I of Qinan Oilfield, and 22 wells were detected with advanced channeling paths. The result is identical with that of the tracer experiment in pilot test unit. According to the in dentified results the plan maps of advanced channeling paths are mapped outto study the distribution regularity controlled by sedimentary microfacies, sand shape and paleocurrent direc tion.
Keywords:advanced channeling paths  K-means clustering procedure  quantitative identification  heterogeneity of reser voir  distribution law
