摘　　要：勘探实践证明,松辽盆地葡萄花油层成藏条件优越,具有“满凹含油”特征,是开展石油资源精细勘探的主力层系,剩余资源主要分布于成熟探区及其周边。优选位于成熟源岩区内的敖南地区作为典型刻度区,利用岩芯、测井和试油等资料,对葡萄花油层的源岩、储层及油藏进行了详细解剖和刻画,认为该区具备3个有利成藏的地质条件:①有效烃源岩控制油气分布范围;②三角洲前缘亚相薄互层砂体构成油气储集层;③砂体、构造匹配发育大面积岩性油藏。通过综合评价,确定敖南地区含油面积为256.3 km^2,采用容积法和油藏规模序列法估算该区资源量为5057.1×10^4 t,并获取运聚系数、可采系数和资源丰度等可代表资源评价的关键参数。The exploration practice has proved that the Putaohua oil-bearing layer in Songliao Basin has superior accumulation conditions and characteristics of“sag-wide oil-bearing”,which is the main target of fine petroleum exploration.The remaining resource are mainly distributed in the high exploration area and its surroundings.The authors selected Aonan area located in the mature hydrocarbon source rock area as typical calibrated area,analyzed and depicted the source rock,reservoir and hydrocarbon accumulation using core,well logs and oil tests.It is believed that this area has three favorable geological conditions for hydrocarbon accumulation.Firstly,effective hydrocarbon source rock controls oil-gas distribution range.Secondly,delta front interbedded thin sand bodies can be good reservoir.Thirdly,assemblage of sand body with structure forms lithostratigraphic trap.Through comprehensive evaluation,the oil-bearing area of Aonan area is delineated as 256.3 km^2,and the resources volume is estimated as 5057.1×10^4 t,using the volume method and reservoir scale sequence method.The hydrocarbon migration and accumulation coefficient,recoverable factor,resource abundance are calculated,which represent key parameters of resource evaluation.
