Abstract: The reservoir forming characteristics of oil and gas resources in Dongliang structural belt of Fuxin basin are studied and evaluated. The source rocks are coal measures strata in the lower part of Shahai formation, the reservoirs are the lower part of Si formation and the middle and upper part of Jiufotang formation, and the mudstones of Jiufotang formation, Shahai formation and Fuxin formation can be used as good caprocks, in which the dark mudstone of Sha 4 member is a regional high quality caprock, and the trap type of Shahai formation in Dongliang area is a compound trap of lithologic trap and structural trap.
Keywords: Fuxin basin; Dongliang structural belt; evaluation of oil and gas resources; coal measures strata; composite trap
阜新盆地多年来做过大量的油气地质勘探、科研等工作,多井见油气显示,但主要的工业油流井和气流井均位于阜新盆地中段东梁构造带(如图1所示)。(剩余3418字)
