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-
