三叠系是阿尔及利亚A区块最有利的勘探目的层。通过对志留系烃源岩的评价分析、三叠系储层特征研究,以及圈闭条件、盖层保存条件和油气成藏时空配置条件等的综合研究,认为A区块控制油气成藏的因素有2个方面:一是烃源条件及有效的油气运移通道是决定A区块油气是否成藏的直接因素;二是储层的储集性能决定油气的富集程度。从已发现油藏实例剖析,本区的油气勘探应把握近油源的原则,在构造精细解释及储层反演、微裂缝预测的基础上,解决好储层和圈闭这2个影响油气勘探的关键因素。
Triassic is the most favorable exploration target for Block A in Algeria. Based on the comprehensive analysis of the Silurian source rocks, the study of Triassic reservoir characteristics, trap conditions, reservoir conditions and space-time conditions for hydrocarbon accumulation, it is considered that Block A controls the hydrocarbon accumulation There are two factors: First, hydrocarbon source conditions and effective hydrocarbon migration channels are the direct factors that determine whether oil and gas accumulate in Block A; second, the reservoir’s reservoir properties determine the degree of hydrocarbon enrichment. From the analysis of the discovered reservoir examples, the principle of near oil source should be grasped in the exploration of oil and gas in this area. Based on the detailed explanation of structure and the prediction of reservoir inversion and microcrack, the two oil and gas reservoirs and traps The key element of exploration.
