【摘要】：苏丹Muglad盆地Fula凹陷是一个陆相被动裂谷盆地内发育的富油气凹陷,经过多期次勘探后,目前已进入新的以岩性圈闭为目标的勘探阶段。以"满凹含油理论"、"构造—层序区带聚集理论"为指导,以岩性油气藏"四图叠合"区带评价方法为手段,对Fula凹陷三级层序内构造、沉积、有效烃源岩、运移条件的配置关系进行了综合分析,并结合现今油气发现,预测了Fula凹陷内岩性油气藏有利勘探区带。分析结果认为:Abu Gabra组AG2段是岩性油气藏发育最有利层段,Jake区扇三角洲前缘相带是目前最有利的岩性油气藏勘探区带,Baleela区曲流河三角洲前缘相带次之,Moga区曲流河三角洲前缘相带再次之,Fula区断裂坡折带上盘岩性油气藏勘探潜力有限。
[Abstract]:The Fula depression of the Muglad basin in Sudan is an oil-gas rich depression developed in the continental passive rift basin. At present, it has entered a new exploration stage with lithologic traps as its target. It is guided by "Man depression oil bearing theory", "tectonic-sequence zone accumulation theory" and by means of the evaluation method of "four map superposition" zones of lithologic oil and gas reservoirs. In this paper, the collocation relationships of tertiary sequence structure, sedimentation, effective source rock and migration conditions in Fula depression are comprehensively analyzed, and combined with the present oil and gas discovery, The favorable exploration zone of lithologic reservoirs in Fula sag is predicted. The analysis results show that the AG2 member of the Fula formation is the most favorable segment for the development of lithologic reservoirs and the fan delta front facies zone in the Jake area is the most favorable lithologic oil and gas reservoir exploration zone at present. The exploration potential of lithologic reservoirs in the fault slope break zone of the Fula area is limited, followed by the meandering river delta front facies belt in the zigzag river delta area and the meandering river delta front facies belt in the Jianguo area.
