摘　　要：对川东北地区飞仙关组开展了聚类分析研究、储层综合分类研究、气水识别研究 ,在此基础上进行储层含气性评价。根据飞仙关组测井数据分布特征 ,将储层聚类分为 3类 ,建立了类中心模型 ,开展了聚类分析 ;利用聚类分析结果 ,结合储层参数特征、储层岩性特征以及测井曲线特征 ,对储层进行了综合分类研究 ,将储层分为Ⅰ、Ⅱ、Ⅲ、Ⅳ类 ;以测试结果为依据 ,选择典型的含气储层和含水储层为样本 ,建立了气水差异识别图版 ,对储层含气水性质进行分辨。综合利用储层分类结果、气水识别结果对储层含气性进行评价。Research on cluster analysis, integrated reservoir classification and gas-water identification is made in the Feixianguan Formation in the northeast area, Sichuan basin, based on which evaluated is gas-bearing capability of reservoir there. According to log data of the Feixianguan Formation, clustering center model is set up for cluster analysis, as a result, the reservoirs in this Formation are clustered into 3 kinds. With the help of cluster analyses, reservoir parameter characteristics, reservoir lithologies and logging curves, reservoirs may be sort out into 4 categories. By selecting the typical log data of gas-bearing beds and water-baering beds as samples of cluster analysis, gas-water difference discrimination cross-plot is worked out. Results of the reservoir classification and gas-water identification are comprehensively used to evaluate the gas-bearing capability of reservoir.
