摘要

昌图凹陷九佛堂组-阜新组可划分出3个中期基准面旋回:MSC1

MSC2和MSC3.除MSC1旋回为一对称旋回外

其它两个旋回均只发育上升半旋回。经井-震对比

这3个中期旋回与地震剖面上划分出的S

和S

有很好的对应关系。经分析

MSC1中扇三角洲前缘沼泽化的煤层、浅湖相泥岩和MSC3中最大洪泛期暗色泥岩是最有利的烃源岩;各旋回中的扇三角洲前缘亚相和水下扇扇中亚相是较好的储集相带。今后的油气勘探中

应将MSC3上升半旋回的中上部和MSC1上升半旋回作为主要的勘探层系。

Abstract

The Jiufutang Fuxin Formations could be divided into MSC1

MSC2 and MSC3 medium term base level cycles

among them MSC2 and MSC3 are elevated semi-cycles.These three cycles correspond well to S

and S

recorded in seismic sections.Accordimg to well drilling and seismic data

the marsh coal-bed in fan-delta front and shallow lake mudstone of MSC1 and the flood dark mudstone of MSC3 are most favourable source rocks;fan-delta front subfacies and subaqueous medium fan subfacies of every cycle are good reservoir facies.It is suggested that the middle and upper parts of MSC3 and MSC1 elevated semi-cycles should be taken as the main exploration sequences.
