摘　　要：鄂尔多斯盆地苏里格东部地区二叠系石盒子组盒8段大面积分布碎屑岩储集层,孔隙类型以次生溶孔及晶间孔为主,喉道类型以弯片状喉道和片状喉道为主,储层非均质性强,属典型的致密砂岩储层。综合利用钻井、测井及分析化验资料,优选储层评价参数,建立了盒8段致密砂岩储层的评价标准,将研究区的储层类型划分为四类。以灰色关联分析法为基础,对苏里格东部盒8段致密砂岩储层进行了评价,克服了储层评价中主观性问题,提高储层综合评价的精确。It is clastic rock reservoir of He8 section in Shihezi formation that distribute at Eastern Sulige gasfield of ordos basin,the main porosity types are the secondary dissolution pore and the crystal the hole,and the throat type main with the curved lamellar throat and the laminated throat,it has strongly anisotropy of reservoir,and it belongs to typical tight sand reservoir.Based on comprehensive utilization of the well drilling,well logging and analysis chemical examination and so on,the article optimize evaluation parameter of the reservoir,and established evaluation criteria of tight sand reservoir of He8 section,at the same time,there are four kinds type of reservoirs in the studying area.Take the gray related analysis as the foundation,through the evaluation of tight sand reservoir in the He8 section of eastern Sulige gasfield,it overcomes the subjective question in the reservoir appraisal,and raises the synthetic evaluation precise of reservoir.
