聚类分析法在胜利油田青东5块储层评价中的应用 The Application of Cluster Analysis Method in Reservoir Evaluation of Qingdong 5 Block in Shengli Oilfield

储层评价是油气藏研究的重要内容，对储层进行合理且有效的评价研究，对油气田勘探开发工作具有重要的意义。本文选取青东5块典型井的孔隙度、渗透率、含油饱和度等储层参数，运用Q型聚类分析方法，对储层进行了分类，将其划分为3种类型，然后做出了3种储层类型在平面上的分布。结果表明，应用Q型聚类分析方法进行储层分类评价是可行、有效的，储层分布的研究结果对于该类型油气田的勘探开发具有一定的应用价值。 Reservoir evaluation is an important part of reservoir research. It is of great significance for the exploration and development of oil and gas fields to make a reasonable and effective evaluation of the reservoir. In this paper, the reservoir parameters of typical wells in Qingdong 5 Block were selected, such as porosity, permeability and oil saturation. And next, the reservoirs were divided into 3 types of reservoirs by Q cluster analysis. Then, the 3 types of reservoirs were distributed on the plane. The results show that it is feasible and effective to apply Q cluster analysis method for reservoir classification and evaluation and the research results of reservoir distribution have certain application value for the exploration and development of this type of oil and gas fields.
