摘　　要：研究了焉耆盆地八道湾组储层储集空间类型及物性特征 ,认为八道湾组储层孔隙不发育 ,储集空间以原生残余粒间孔和残余粒内溶孔、裂缝为主 ,属低孔、低渗特低渗储层 ,并对八道湾组储层发育控制因素进行了分析研究。根据储层发育的状况 ,以压汞参数作为储层定性评价的定量指标 ,把焉耆盆地侏罗系八道湾组的储层分为 5类 。The type of reservoir space and its physical properties in Badaowan Formation of Yanqi basin are studied. It is considered that in Badaowan Formation the reservoir pore is not grown enough, the reservoir space is mainly consisted of primary residual intergranular dissolved pore and fractures, which belongs to low pore, low permeability reservoir. The control factors to the reservoir growth in Badaowan Formation are analytically studied. Based on the conditions of reservoir growth, the reservoirs in Badaowan Formation of Jurassic system of Yanqi Basin are divided in 5 kinds by using the mercury intrusion parameters as the quantitative indications of reservoir qualitative evaluation, thus the beneficial areas for future exploration are given.
