摘　　要：在储层综合评价中,评价参数的选择、权重系数的确定等均存在主观人为因素的干扰,如何合理、客观地对储层进行综合评价显得尤为重要.以白豹地区延长组长6储层为例,运用特征选择分析、灰关联分析、聚类分析等方法进行储层综合评价,将研究区长6储层划分为4类,其中Ⅰ类储层和Ⅱ类储层作为研究区的最好和较好储层,是寻找油气的有利区带.研究区预测井位的试油日产油量分析结果与通过储层综合评价方法预测出的结果一致.该评价方法确定储层分类方便、有效,并提高了该区块的解释符合率.In the comprehensive evaluation of reservoir,the choice of assessment parameter and the determination of weight coefficient are all influenced by human subjective factors.Chang 6 reservoir in Baibao Oilfield is comprehensively evaluated by using feature selection analysis,grey relational analysis and cluster analysis,and it is classified into 4 types of reservoirs.Among them,typeⅠand type Ⅱ of the reservoirs are regarded as the best and better reservoir types,and they are the favorable zones in hydrocarbon exploration.The prediction result of the oil output based on the evaluation method is in accord with the daily yield of the oil testing wells in the studied area,which shows the evaluation method is effective.
