The U.S. Strategic Petroleum Reserve is an emergency supply of oil in case of natural disasters, national security incidents and other events. It is maintained by the Energy Department. It is estimated that there are about 605 million barrels of oil in the reserve.
美国战略石油储备是在发生自然灾害、国家安全事件等情况下的一种紧急石油储备。它由美国能源部维护。据估计该储备约有6.05亿桶石油。

The release is meant to lower fuel costs and serve as a warning to the Organization of Petroleum Exporting Countries (OPEC). OPEC is a group of 15 mostly Persian Gulf countries. The U.S. and other major oil users believe high prices could slow the global economy's recovery from the pandemic.
此次释放储备旨在降低燃油成本，并向石油输出国组织（欧佩克）发出警告。欧佩克是由15个主体为波斯湾国家组成的组织。美国和其它主要石油消费国认为，高油价可能会减缓全球经济从大流行中的复苏。

The move is also aimed at U.S. voters who are dealing with high inflation and rising gas prices ahead of winter holiday travel. Gasoline prices are, on average, more than 50 percent higher than a year ago, the American Automobile Association said.

Officials said it was the first time that the United States had made such a move with some of the world's largest oil users. The release of the reserves would be a mix of an exchange and a sale to companies that Congress approved, American officials said.
有关官员表示，这是美国首次与全球最大的一些石油消费国联手采取这样的行动。美国官员表示，释放的石油储备将会通过交换和销售结合提供给国会批准的公司。

The actions by the U.S. and other nations risk angering some countries, especially Saudi Arabia and Russia. Saudi Arabia and other Gulf countries have made clear that they want to control the oil supply to keep prices high for now. There have been warnings that those countries may back away from promises to increase supplies in coming months.
美国等国的行动可能会激怒一些国家，尤其是沙特和俄罗斯。沙特和其它海湾国家已明确表示，他们眼下希望控制石油供应以维持高价。有警告称，这些国家可能会放弃未来几个月增加供应的承诺。

The Biden administration decision comes after weeks of diplomatic talks. Biden and Chinese President Xi Jinping talked about ways to deal with oil supplies in their online meeting earlier this month. The two "discussed the importance of taking measures to address global energy supplies," the administration said.
拜登政府的决定是在经过数周的外交谈判之后做出的。拜登和中国国家主席习近平在本月初的视频会议上讨论了应对石油供应的办法。美国政府表示，两人“讨论了采取措施解决全球能源供应问题的重要性。”

The pandemic severely affected energy markets. As business closures began in April, 2020, demand fell. Energy traders did not want to buy large amounts of oil that they could not store. But as the economy recovered, prices jumped to a seven-year high in October.
大流行严重影响了能源市场。随着2020年4月开始的企业停业，需求下降。能源交易商不想购买他们无法储备的大量石油。但是随着经济复苏，石油价格在10月份跃升至7年以来的高位。

Experts say releasing reserves may not be enough to prevent continuing price increases.
专家表示，释放石油储备可能不足以阻止价格持续上涨。

"It's not large enough to bring down prices in a meaningful way and may even backfire" if OPEC countries slow their supply of oil, Caroline Bain told Reuters. She is an economist at Capital Economics, a research business.
卡罗琳·贝恩对路透社表示，如果欧佩克国家减缓石油供应，“那么释放石油储备不足以给油价带来有意义的降价，甚至可能会适得其反。”她是凯投宏观的经济学家，这是一家研究公司。

Biden and administration officials said that releasing more oil from the reserve is not in conflict with the president's long-term climate goals. They said the release is a short-term answer to a current problem. Climate policies are a long-term answer over many years, they said.
拜登和政府官员表示，释放更多石油储备跟总统的长期气候目标并不冲突。他们表示，这次释放是对当前问题的短期解决方案。他们表示，气候政策是多年来的长期解决方案。
