利比亚古达米斯盆地含油气系统研究

Study on the Oil and Gas System in Ghadames Basin in Libya

利比亚古达米斯盆地是一个巨大的撒哈拉台地克拉通内盆地,该盆地对于利比亚乃至北非都是一个重要的含油气盆地,对于整个非洲大陆油气的形成和储集具有重要影响。在分析盆地地质构造特征和沉积演化特征的基础上,进一步探讨了盆地烃源岩、储集层和盖层的演化发育历史形态,并对盆地内2个较为重要的含油气系统进行了剖析,为在该盆地内进一步开展石油勘探开发工作提供了可靠依据。

The Ghadames Basin in Libya is a large intracratonic basin of the Saharan Platform. The basin has obvious tectonic evolution characteristics throughout geological time. The basin is the important one in Libya and North Africa,the influence of the basin to the formation and storage of oil and gas re- sources in African continent is important. Based on analyzing the geological tectonic characteristics and sedimentation evolution characteristics of the basin, the history form of evolutionary development of the hy- drocarbon source rocks, reservoir and cover of the basin is discussed, besides that the two important oil and gas system of the basin is also studied, so as to provide some reliable reference for further conducting oil exploration and development work in the basin.
