利比亚古生代含油气盆地油气发现影响因素分析

利比亚发育6个含油气盆地,其中4个为古生代含油气盆地,分别是古达米斯盆地、木祖可盆地、库佛腊盆地和昔兰尼加盆地,已发现储量占全国总储量9%,其余储量主要分布在两个中、新生代盆地。通过对已有发现油田和盆地勘探历程的研究,总结影响古生代含油气发现的因素有3个,分别是石油地质条件、勘探程度和国际形势及国内政策影响,其中,石油地质条件占主导地位。4个古生代盆地中石油地质条件较好的盆地是古达米斯盆地和木祖可盆地。随着近年该国与美国关系的缓解及有利的国内政策,古生代盆地特别是木祖可盆地勘探投入不断增加,近年不断出现新发现,成为该国近年及未来的一个勘探热点地区,也是中国油公司进入该国值得关注的地区。

Analysis of Influencing Factors on Hydrocarbon Discoveries in Paleozoic Hydrocarbon Basins,Libya

There are six hydrocarbon basins in Libya, in which four are Paleozoic hydrocarbon basins, i.e., the Ghadamis Basin, the Murzuq Basin, the Kufra Basin, and the Cyrenaica Basin. The proved reserves of the basins account for 9% of the total in the whole country. Other reserves centralize in Mesozoic and Cenozoic basins. Based on the study of the exploration history of the oilfields and basins with hydrocarbon discoveries, three factors influencing Paleozoic hydrocarbon discoveries are recognized, namely, the ...
