摘要:

采用盆地构造解析理论和方法综合研究了穆格莱德盆地Fula凹陷油气藏的控制因素。该凹陷发育了Abu Gabra组优质烃源岩和3套生、储、盖组合,第1套为Abu Gabra组自生自储自盖;第2套为下生上储盖的大组合,即Abu Gabra组生、Bentiu组储和Darfur群盖;第3套组合为Abu Gabra组生,Darfur群储、盖。它们都是有利的勘探组合:断层控制油气运移和聚集,构造背景和砂体展布控制油气分布,区域盖层控制油气富集。凹陷中部构造带是油气主要聚集区,有良好的勘探前景。

Abstract:

To study the enrichment patterns of oil and gas in Fula depression of Muglad basin, Sudan, the reservoir control factors are studied with analysis theory of basin structure. In Fula depression, Abu Gabra Formation developed in Early Cretaceous is an effective hydrocarbon source rock, and three sets of source-reservoir-cap rock assemblages are also developed, among which Abu Gabra is a favorable assemblage of in-situ source and reservoir, while the second set is composed of source rock in Abu Gabra, channel sandstone reservoir in Bentiu and shale seal in Darfur Group,the third set is characterized by Abu Gabra generating, Darfur Group collecting and sealing; they are all favorable assemblages which have the advantages that the oil and gas migration is controlled by fault,and the distribution by the geological structure background and sand distribution, the enrichment by regional caprock. The central structure belt in Fula depression is the main bonanza pool which is a potential area for oil and gas exploration.

Key words: hydrocarbon enrichment, hydrocarbon exploration, half-horst or horst, effective source rock, Fula depression, Muglad basin
