摘　　要：依据焉参1井、宝1井和焉2井5个层7个油气样的PVT相态特征分析，结合多种经验统计法综合判刑焉者盆地油气藏类型为：宝浪油田宝中区块Ⅳ油组为带油环的凝析气箴或凝析气预油藏，宝北区块和本布图油田焉2区块为富含中间怪的轻质黑油油藏，以上认识为下步勘探寻找油环储量指明了方向，为油田开发方案编制提供了重要依据．Combining with severial experience stutistical methods,the hyd1ocarbon reservoir types in Yanqi basin arecomprehensively discriminated on the basis of PVTphase behaviour analysis of 7 hydrocarbon samples pickedfrom 5 zones in Well Yanchan l,We1l Bao l and WellYan 2.The IV Zone in Baozhong block in Baolang oilfieldis either a condensate gas reservoir with oil rings or an oilreservoir with a condensate gas cap, whi1e Baobei blockand Yan 2 block in Benbutu oi1field are 1ight b1ack oilreservoirs with rich intermediate hydrotarbons.These studyresultS point out the direction for further exp1oring oilring reserves and provide an important basis fordevelopment planning.
