摘要
西北非油气资源丰富,是我国石油公司海外油气勘探的重要区块。受泛非、加里东、海西、阿尔卑斯运动的影响,西北非构造演化经历了泛非期基底形成、古生代稳定陆块演化、中生代裂陷、新生代反转隆升的复杂过程,发育三叠、伊利兹、锡尔特等多个超大型含油气盆地。主要有两套成藏组合:撒哈拉地台为主的古生代成藏组合、北部大陆边缘为主的中新生代成藏组合。
There are an abundance of petroleum resources in Northwestern Africa. It has become hot spots of oil and gas exploration in the world. It is also one of abroad risk exploration areas of Chinese petroleum corporations. Due to being influenced by Pan Africa, Caledonian, Hercynian and Alpine movements, Northwest Africa has un- dergone complex tectonic evolution processes, such as basement formation （Pan Africa event ）, stable continental block evolution （Paleozoic）, rifting （Mesozoic）, tectonic reversal （Cenozoic）. The tectonic movement was intensive in the northern of Northwest Africa in Mesozoic and Cenozoic so that the Atlas belt uplifted. However, the Saharan platform was nearly stable at that time. There are many great petroliferous basins, such as Triassic basin, Illizi basin. Sirte basin. It can be divided into two kinds of plays： Paleozoic play and Mesozoic-Cenozoic play. The former is mostly in Saharan platform, in which the stratigraphic and structural reservoirs are the main reservoirs. The latter is mostly in north continental margin, in which almost all are structural reservoirs.
