摘　　要：以渤中19-6大型变质岩潜山凝析气藏为例,综合利用钻井取心、野外露头、测录井、化验分析、产能测试等资料,研究新太古界潜山储层岩性特征、储集空间特征和主控因素,分析总结潜山岩石类型、优势岩性、主要储集空间类型,以及影响潜山储层发育的主导外因、主导内因等影响因素。本研究成果对渤海湾盆地新太古界潜山油气藏的勘探开发有一定的指导意义。Taking BZ19-6 large metamorphic buried hill condensate gas reservoir as an example,the lithological characteristics,reservoir space types,and main controlling factors of the Neoarchean buried hill reservoirs were studied,by comprehensive utilization of drilling coring,field outcrop,logging,and laboratory analysis data,and production test data.And then it was summarized the buried hill rock types,dominant lithology,main reservoir space types,and the dominant external and internal factors that affect the development of buried hill reservoirs.The study results have certain guiding significance for the exploration and development of buried hill oil and gas reservoirs in Bohai Bay Basin.
