据美洲润滑油周刊10月6日消息，7月份美国润滑油基础油产量有所下降，略低于6月份的产量，并在连续两个月高于新冠疫情爆发前的水平后首次低于新冠疫情爆发前的产量。
美国能源情报署(EIA)上周公布的数据显示，7月份美国炼油商生产了560万桶矿质基础油，而此前一个月的产量为570万桶。与2020年7月的490万桶相比，产量增加了15%。但7月份的产量比2015年至2019年(冠状病毒大流行前五年)该月的平均水平低4%。
今年6月和5月美国润滑油基础油产量比新冠疫情爆发之前这两个月的五年平均水平分别高出4%和2%。
去年5月和6月，美国基础油产量在最严格的防疫封锁时期触底后，下半年开始持续回升。去年11月，产量恢复到疫情前的水平，今年1月产量再次恢复到疫情前的水平。2月，由于西南部异常寒冷的天气导致炼油厂关闭，产量回落。
美国EIA将于本月底公布8月份的数据，届时可能会显示，由于8月27日袭击墨西哥湾沿岸的飓风“艾达”的影响，基础油产量进一步下降。墨西哥湾沿岸地区占美国基础油产能的很大比例，几家工厂在飓风面前暂时关闭。不过，这次风暴造成的破坏很小，因此对基础油产量的影响可能会小于其他一些造成更大破坏的风暴。
7月份美国基础油产量下降全部来自石蜡基油市场。炼油商当月的石蜡基油的产量为470万桶，低于今年6月的490万桶，比疫情爆发前5年同期的平均水平低6%。环烷基油产量达到90.2万桶，高于6月份的80万桶，比疫情前的五年平均产量高出6%。

U.S. base Oil Output Shrank in July
base oil output in the United States retreated in July, dipping slightly below the level produced in June and falling below amounts produced before the COVID-19 crisis after two consecutive months of running ahead.
The nation’s refiners produced 5.6 million barrels of mineral base oils in July, according to data published last week by the U.S. Energy Information Agency, after churning out 5.7 million barrels the previous month. The total was up 15% from 4.9 million barrels in July 2020. July’s total was 4% lower than the average for that month from 2015 to 2019 – the five years before the coronavirus pandemic.
Output for June and May of this year was 4% and 2% higher than the respective five-year averages for those months preceding COVID-19. The July output was up 15% from 4.9 million barrels in July 2020.
U.S. base oil production steadily rebounded during the second half of 2020 after bottoming out in May and June of last year, when lockdown measures aimed at containing the pandemic were at their most stringent. Output returned to pre-pandemic levels in November of last year and again in January of this year before falling back in February due to refinery shutdowns caused by unusually severe cold weather in the Southwest that month.
When the EIA publishes data for August at the end of this month it could show a further decrease in production due to impacts from Hurricane Ida, which struck the Gulf of Mexico coast align="justify"> The July decline all came from the paraffinic segment of the market. Refiners made 4.7 million barrels of paraffinic base stocks that month, down from 4.9 million barrels in June of this year and 6% less than the average for that month in the five years before the pandemic. Output of naphthenic oils reached 902,000 barrels, up from 800,000 barrels in June and 6% higher than the five-year average preceding the coronavirus crisis.
