Differences of petroleum geological conditions between eastern and western basins in Algeria

CNOOC Beijing Research Institute, Beijing 100027, China

摘要

摘要: 勘探实践表明,阿尔及利亚的油气产量主要来自撒哈拉地台东部的含油气盆地区,而西部含油气盆地区勘探程度较低,勘探前景广阔。东西部盆地两者从盆地沉积充填、烃源岩、储层、圈闭、油气性质和油气成藏模式等方面均表现出明显的差异性。勘探潜力分析认为,西部盆地区油气勘探程度低,应以天然气为主攻方向,瞄准断裂带附近发育的大型背斜构造圈闭;东部盆地区油气勘探程度相对较高,油气勘探应以找油为主,寻找中小型的构造圈闭或岩性—构造复合圈闭。

Abstract: Based on several years of petroleum exploration and development in Algeria, the most of petroleum production are from the eastern basins on the Saharan Platform, while the western basins have large prospecting potential but with low exploration degree. The eastern and western basins are evidently different from each other in their sedimentary fillings, source rocks, reservoirs, traps, petroleum properties and accumulation models. Analysis suggests that large anticline traps related to fault belts are advantageous to find natural gas accumulation in the western basins with low exploration degree. By comparison, due to high exploration degree and exploration difficulties, oils in middle and small size structural traps or lithologic-structural traps should be targeted in the eastern basins.
