三肇凹陷葡萄花油层地质条件复杂、区块较多.在评价单元划分的基础上,结合研究区的具体地质特征和开发动态特征,采用聚类分析方法,结合各参数的地质意义和开发意义,优选出6个地质参数和4个开发参数.在单因素评价的基础上,针对单因素分类评价存在的分类结果不唯一问题,进行了多因素综合定量评价,并建立分类标准,根据分类标准可以将三肇凹陷葡萄花油层已开发区块划分为三类.Ⅰ类区块在地质上和开发上好于Ⅱ类区块,Ⅱ类区块优于Ⅲ类区块,分类评价结果与实际地质特征和开发特征相符合.%With complicated geological conditions, Putaohua oil layer in Sanzhao depression has lots of blocks.On the basis of evaluation unit division, geological characteristics and development dynamic characteristics, combined with the significance of geological parameters and development parameters, The method of cluster analysis and optimized 6 geological parameters and 4 development parameters is adopted.As the classification of single factor evaluation has not the only result, the multi-factor comprehensive quantitative evaluation is adopted to set up the classification standard.According to the classification standard, the developed blocks of Putaohua oil layer in Sanzhao depression are divided into three types including Ⅰ , Ⅱ and Ⅲ class blocks.As a result of classification evaluation, the geology and development of Ⅰ class blocks are better than Ⅱ class blocks as well as Ⅱ class blocks are better than Ⅲ class blocks, which is close to actual geological characteristics and development characteristics.
