摘　　要：为提高准噶尔盆地阜康凹陷东部斜坡区齐古组储集层产能,选取孔隙度、渗透率、石英体积分数、粒径、非均质性系数、异常压力系数、压实作用、方解石和绿泥石胶结物体积分数与单砂体厚度作为储集层产能评价参数,分别利用灰色关联法和主成分分析法对区内齐古组产能进行综合定量评价和分类。结果表明:两种方法可定量计算各评价指标的权重系数,其中目的储层产能受压实作用影响最大;基于综合评价标准,将齐古组储集层划分为3类,分类结果与齐古组开发现状吻合,表明运用灰色关联法和主成分分析法评价储集层产能可行性均较好。The productivity of reservoirs in Qigu Formation was evaluated by 9 indexes,such as porosity,per-meability,volume fraction of quartz,grain size,coefficient of anisotropy,abnormal pressure coefficient,compac-tion effect,volume fraction of calcite and chlorite,single sand body thickness were used to make evaluation and classification on productivity in reservoirs,all of which would improve productivity in reservoirs of Qigu For-mation on the Fudong Slope of Junggar Basin.The result showed that the weight coefficient of each factors could be quantitatively calculated by two analysis methods,productivity of reservoirs in Qigu Formation was mainly controlled by compaction;Based on evaluation standard,reservoirs in Qigu Formation were divided into three types,and classification was anastomosed with current exploration and development situation,which showed feasibility of two methods was good.
