为了指导安塞油田化子坪井区长2油藏的开发生产，针对该区的储层特征，采用动静态资料相结合的方法，选取孔隙度、渗透率、日产原油量三项参数作为长2储层流动单元的划分参数，应用聚类分析法和判别分析法把长2储层划分为四类流动单元。对四类流动单元的岩性特征、物性特征、微观孔隙结构特征、沉积微相特征以及生产动态特征进行了分析。研究结果表明：较好的流动单元渗透能力和储存能力较强，日产油量也较高。该研究方法对相似地区储层流动单元的划分有借鉴意义。
為瞭指導安塞油田化子坪井區長2油藏的開髮生產，針對該區的儲層特徵，採用動靜態資料相結閤的方法，選取孔隙度、滲透率、日產原油量三項參數作為長2儲層流動單元的劃分參數，應用聚類分析法和判彆分析法把長2儲層劃分為四類流動單元。對四類流動單元的巖性特徵、物性特徵、微觀孔隙結構特徵、沉積微相特徵以及生產動態特徵進行瞭分析。研究結果錶明：較好的流動單元滲透能力和儲存能力較彊，日產油量也較高。該研究方法對相似地區儲層流動單元的劃分有藉鑒意義。

In order to guide the development and production of Chang-2 reservoir in Huaziping area, Ansai oilfield, the method of combining dynamic data with static data is adopted according to the reservoir characteristics of the area. Taking three parameters of porosity, permeability and daily oil production as split parameters of flow units, Chang-2 reservoir is divided into four flow units by using cluster analysis and discriminant analysis. Their lithologic characteristics, physical characteristics, microscopic pore struc-ture characteristics, sedimentary microfacies characteristics and production performance characteristics are analyzed. The research shows that good flow units possess strong penetration ability and storage ability, getting higher daily oil production as well. This re-search method has some reference for the division of reservoir flow units in similar areas.
