摘　　要：为分析岩溶储层类型、发育特征及其与油气的关系,以塔里木盆地轮古西奥陶系潜山油藏为例,开展储层精细描述,从钻、录井显示、岩心、常规及成像测井、地震资料等方面描述岩溶储层特征,并运用生产动态测试资料进行评价.结果表明:该潜山岩溶储层主要发育洞穴型、裂缝孔洞型、孔洞型和裂缝型4类储层,其中洞穴型中的洞穴连通型储集空间组合地层能量供应充足,具有一定的上产稳产期,整体开发阶段产量递减缓慢,为最好的储层类型.岩溶储层的发育和油气富集程度与其距潜山面的距离密切相关,潜山面向下50m范围内储层最为发育,油气最为富集.In order to recognize the characteristics of reservoir types and the relation between reservoir and petroleum,The Ordovician carbonate reservoir of West Lungu was chosen as an object of study.The data of drilling,logging,seismic,testing and production performance were applied in this research,and the comprehensive evaluation of the characteristic of the reservoir were made.This study draws the conclusion that the carbonate reservoir can be divided into four types:cavity type,fracture +vug type,vug type and fracture type.And the high connectivity cavity type is the best reservoir,with a relatively long period of stabilized production,the producing energy is sufficiency and production decline is slowly.This study also points out that the quality and oil accumulation of the reservoir has the osculating correlation with the distance between the reservoir and buried hill,the reservoir precinct from buried hill were less than 50 meters,this region were oil enriched zone and the reservoir were highly developed.
