摘要：

苏丹Muglad盆地东北部AG组可以划分为下部层序、中部层序和上部层序。下部层序形成于盆地裂陷早期,以粗碎屑快速堆积为主。中部层序形成于盆地扩张期,是Muglad盆地生油层和储集层发育的重要层段。上部层序形成于盆地萎缩期,以河流相沉积为主。综合评价认为中部层序具有良好的生储盖组合,是Muglad盆地AG组的重要勘探层系。中部层序的东部缓坡带是最有利的勘探区带,Ⅰ号目标是较成熟的勘探目标。

关键词: Muglad盆地, 层序地层, 勘探层系, 勘探区带, 勘探目标

Abstract:

AG Formation in northeastern Muglad Basin of Sudan can be divided into lower,middle,and upper sequences.The lower sequence, formed in the early chasmic stage of the basin,mainly consists of rapidly accumulated coarse sediments.The middle sequence,deposited in the spreading period of the basin,is an important interval with well developed source and reservoir rocks in Muglad basin.The upper sequence is mainly composed of fluvial formations, deposited in the shrinking stage of the basin.Comprehensive evaluation shows that the middle sequence with favorable combination of source,reservoir and cap rocks is an important series of strata for exploration in AG Formation in Muglad basin.The middle sequence in the eastern gentle slope zone is the most favorable play,where the prospect I is a relatively mature exploration target.

Key words: Muglad basin, sequence stratigraphy, series of strata for exploration, play, exploration target
