The Quseir Formation consists mainly of dark gray mudstones with a high organic matter content and excellent hydrocarbon‐generating potential. The main objectives of this study are to highlight the dominant structural elements in the Komombo Basin, Egypt, and evaluate the geochemical characteristics of the Quseir Formation. Depth maps and a 3D structural model indicate two normal fault trends NW–SE and ENE–WSW. The NW–SE trend is the dominant one that created the primary half‐graben system. The depth to the top of the Quseir Formation gradually decreases from the eastern and central parts towards the corners of the basin. The thickness of the Quseir Formation ranges from about 300 to 1000 ft. The 3D facies model shows that the shale has a large probability distribution in the study area, compared with the sandstone and siltstone. The source rock potential varies between good in the western part to very good in the eastern part of the basin. The organic‐rich interval is dominated by gas‐prone kerogen type III based on TOC and Rock‐Eval. The pyrolysis data vitrinite reflectance (%R_o) (0.5–0.74%) and T_max values (406–454C°) suggest a maturity level that ranges from immature to early maturity stage for hydrocarbon generation.

埃及Komombo盆地Quseir组的三维结构模拟和烃源岩评价

Quseir组主要由深灰色泥岩组成，这些泥岩具有较高的有机质含量和极好的生烃潜力。这项研究的主要目的是突出埃及Komombo盆地的主要构造元素，并评估Quseir组的地球化学特征。深度图和3D结构模型指示了两个正常断层趋势NW​​–SE和ENE–WSW。NW–SE趋势是创建主要的半graben系统的主导趋势。Quseir组顶部的深度从东部和中部向盆地的各个角落逐渐减小。Quseir地层的厚度范围从300到1000 ft。3D相模型表明，与砂岩和粉砂岩相比，页岩在研究区域具有较大的概率分布。烃源岩的潜力在盆地西部的良好品位到盆地东部的良好品位之间变化。富含有机物的层段由基于TOC和Rock-Eval的易生干酪根类型III决定。热解数据镜质体反射率（％）R _o）（0.5–0.74％）和T _max值（406–45​​4C°）表明，成熟度范围从生烃到未成熟阶段。
