来源：新华网 据美国能源信息局数据，截至今年9月，美国每天从委内瑞拉进口逾十万桶原油。委内瑞拉在美国进口 石油来源国中排名第十。美国每天分别从沙特阿拉伯和加拿大进口原油25.4万桶和410万桶。 相比当前情况，美国过去几十年更依赖委内瑞拉石油。据美国有线电视新闻网报道，这不仅因为美国距 离委内瑞拉较近，还因为委内瑞拉石油因其黏稠、淤渣较多的特质而更便宜。美国投资咨询企业"价格 分析期货"高级分析师菲尔·弗林说，大部分美国炼油厂是按照加工委内瑞拉石油的标准建成的。这些炼 油厂用委内瑞拉石油而非美国石油进行生产的效率更高。 美国自2005年开始对委内瑞拉实施制裁。2019年1月两国断绝外交关系后，美国不断加大对委经济制 裁，包括禁止委原油出口。2022年11月，时任美国总统拜登豁免美国雪佛龙石油公司及其子公司，允许 其重新在委内瑞拉有限制地进行石油开采与勘探作业。美国总统特朗普今年2月26日宣布，撤销上述豁 免安排，后来又以任何相关收益不得归于委内瑞拉政府为条件予以恢复。 委内瑞拉已探明石油储量3000亿桶，约占全球已探明储量的17%，居世界首位。20世纪末，委内瑞拉最 多日产原油350万桶。受美国封锁等原因影响 ...
