摘　　要：春光探区虽然为源外地区成藏,但是具有垂向上多层系含油、平面油气分布广泛的特征,这与油气输导体系具有密切联系。研究表明,春光探区发育了厚砂层、不整合和断层3类输导体系;3类输导体系相互配置,形成了高效的网毯输导体系。确定了从生烃凹陷到春光探区的长距离油气输导格架和内部3类短距离输导格架,最终建立了春光探区油气输导模式。长短距离输导格架综合配置形成的复式输导体系控制春光探区的油气成藏。Although Chunguang area is an accumulation where there is no oil source,it is featured by multiple oil layers vertically and extensive distribution of oil/gas horizontally,which is in close relation to the oil/gas conduction system. Research indicates three types of conduction systems,namely,thick sandstone,unconformity and fault,developed in Chunguang area. The 3 types of conduction systems exist one in another,forming an effective conduction system in the form of meshwork and carpet. Long-distance oil/gas conduction framework from hydrocarbon-generation sag to Chunguang area and 3 types of short-distance internal conduction frameworks have been verified,which is used to establish the oil/gas conduction mode in Chunguang area. The comprehensive layout of long-distance and short-distance conduction frameworks form the compound conduction system,which controls the oil/gas reservoir forming in Chunguang area.
