| 摘 要： | 根据层序地层学及动力沉积学原理，结合开发层系需要，将齐108块莲花油层分为3个油层组10个砂岩组，该油层可识别出Gm，Ss，Sm，Smg，Sp，Sw，Sh，Sr，Sm，Sf和Sds等11种岩石（性）相，它们构成了二级扇三角洲沉积模型，细分出水下分流河道、前缘砂坝等７种沉积微相，利用古河道趋势分析法，编绘了不同时期砂体的分布网络及沉积微相图，砂体分布明显受控于水下分流河道的展布趋势，不同级别水下分流河道砂体构成了研究区的主要储集层，控制了储层的非均质性，并讨论了沉积微相研究在油田开发中的作用。

| Abstract: | Qi 108 is a small oil developing block of Huanxiling oilfield in Liaohe basin. The reservoir, the third member of Shahejie Formation, consists of fan-delta deposits. Based on the theory of sequence stratigraphy and dynamic sedimentology, with the need of oil developing bed, the Lianhua reservoir of Qi 108 can be divided into three oil bed groups containning ten sandstone beds. The reservoir is recognized 11 lithofacies as follows: Gm, Sm, Ss, Smg , Sp, Sw, Sh, Sr, Fm, Ff and Fds. 12 lithofacies assemblages are composed of the 11 lithofacies, and they are: Gm→Sp→Sm→Fm, Gm→Smg→Fm, Ss→Sm→Sr→Fm; Sm→Sh→Fm, Ss→Sm→Sr→Fm; Gm→ Sm→Fm; Ff→Sr→Sm, Fm→Sw→Sh; Fds→ Sr→Sh→Fm, Fm→Fds→Sw→Sr→Ff; Sm→Sr→Fm; Ff→Sr→Fm. The lithofacies and assemblages constitute subaqueous fan-delta depositional modelling, containing 1) subaqueous major distributary channel, 2) subaque- |
