摘要
阿尔及利亚三叠盆地区域成藏地质条件十分优越,通过地震衰减估计,认为中北部含油气的可能比较大,东南部油气分布范围比较小。纵向上发育有多套含油层系,自上而下为寒武系、奥陶系、志留系、泥盆系、石炭系、三叠系,以三叠系油藏最为发育,占油藏总数的50%,其次为志留系和泥盆系。该区的构造、油气源、生储盖、海西不整合面等是油气富集的主要控制因素。显示了本工区有着良好的勘探前景。
This area has extremely advantageous geological conditions. The estimates of seismic attenuation, shows that mid-north part of Triassic Basin has large possibility to accumulate hydrocarbon, the south-east part is opposite. One of the most common factors is that Triassic Basin develops six sets of on the vertical. Such as Cambrian system, Ordovician system, Silurian system, Devonian system, Carboniferous system and Triassic system. Among these oil-bearing layers, the Triassic system is 50 percent. The advantageous geological conditions are the main controlling factor, which including construction, oil and gas source, reservoir cover and Hereynian unconformity. The author concludes this area is of a certain exploration prospect.
