摘要 升平油田是三肇凹陷东北部在古凸起上继承发育形成的鼻状构造。本文综合分析岩心、测井、录井特征等,探讨了升平油田葡萄花油层沉积相类型。结果表明本区为浅水河控三角洲相,垂向上是水退至水进的过程,发育由三角洲外前缘—三角洲内前缘—分流平原—三角洲内前缘—三角洲外前缘的沉积旋回,重点层PI4-6为最大水退点,发育三角洲分流平原沉积,且可进一步细分为分流河道、决口河道、废弃河道、天然堤、决口扇、溢岸砂和分流间泥7类沉积微相。 Shengping oil field is a nosing structure in the northeast of Sanzhao depression, which is formed on ancient uplift belt. Based on the comprehensive analyzing of the core and the logging, this paper discusses the types of sedimentary facies of Putaohua oil layer in Shengping Field. The results show that Putaohua oil layer in the Shengping oil field is the shallow lacustrine Fluvial-Dominated Delta, there is Depositional cycles of regression and then transgressive In the vertical. As maximum water withdrawal points, PI4 to PI6 is the delta diversion plains deposition ,which Including seven sedimentary microfacies of distributive Channel, burst river, abandoned channel, levee, crevasse fan, overbank sand and interdistributary mud.
