摘　　要：综合应用地震测井岩心等资料,建立了研究区等时地层格架,将三肇周边地带扶余油层层序划分为一个长期基准面旋回和3个中期基准面旋回。三肇周边地带扶余油层发育大型浅水三角洲沉积,可划分为三角洲平原、三角洲前缘和前三角洲亚相3种亚相12种微相。三肇周边地区油水分布关系复杂,单井垂向上存在上油下水、混合型、纯油型、全水型4种模式。三肇周边区带主要发育构造油藏和岩性油藏二大类油藏,岩性上倾尖灭、断层岩性、断块、断鼻、断背斜五个亚类油藏。Basedonseismic logging, core data, isochronous stratigraphic framework in the areawasestablished, SanzhaodepressionFuyureservoirlayer sequencewasdivided into a long-term base level cycle and three medium-term base level cycles.
