【摘要】：近年来,页岩气勘探开发热潮席卷全球,成为目前能源领域关注的热点,并极大的改变了全球油气市场,产生了巨大全球政治经济影响。利比亚作为非洲石油储量之首,也将非常规勘探作为提高本国油气产量的重要手段。据美国能源信息署2013年公布数据,利比亚页岩油资源为260亿桶,页岩气技术可采资源量为290万亿ft3,是非洲最具页岩油气资源潜力的国家;同时,利比亚是北非最主要烃源岩——志留系页岩的沉积中心,蕴含的页岩油气资源非常丰富。但利比亚页岩油气研究相对滞后,本文利用页岩气资源评价方法,分析利比亚主要盆地富有机质页岩分布特征,预测页岩油气资源潜力并划分有利区,认为下志留统Tannezuft页岩和中上泥盆统Frasnian页岩是利比亚重要的页岩勘探层位,且Ghadames盆地的各项页岩评价参数较好,是值得进行页岩气勘探重点地区。
[Abstract]:In recent years, the shale gas exploration and development boom has swept the world and become a hot spot in the energy field. It has greatly changed the global oil and gas market and had a huge global political and economic impact. Libya is the first oil reserves in Africa. Unconventional exploration is also being used as an important means of boosting oil and gas production in the country. Libya's shale oil resource stands at 26 billion barrels, according to data released by the US Energy Information Agency on 2013. With a recoverable resource of 290 trillion ft3, the shale gas technology is the country with the greatest shale oil and gas potential in Africa, and Libya is the depositional center of the Silurian shale, the most important source rock in North Africa. The shale oil and gas resources are very rich in Libya, but the study of shale oil and gas in Libya is relatively lagged behind. In this paper, the distribution characteristics of organic matter rich shale in main basins of Libya are analyzed by using the method of shale gas resource evaluation. It is considered that Tannezuft shale of Lower Silurian and Frasnian shale of middle and upper Devonian are important shale exploration horizon in Libya, and the evaluation parameters of shale in Ghadames basin are good. Is worthy of shale gas exploration in key areas.
