据今日油价网站9月8日消息 美国天然气价格在周二下跌3%后，周三早些时候上涨8%，创下多年新高，主要原因是供应紧张，库存水平较低，因为预计美国西部和南部大部分地区的制冷需求从中到高。
截至美国东部夏令时周三上午10:28，美国基准亨利中心的价格飙升7.68%，达到4.927美元/百万英热单位。
9月下旬的模型预测了高温天气，预计这将推动天然气需求。
根据NatGasWeather网站9月7日至13日的模型，本周美国北部的全国需求将较低，但美国西部和南部的需求将从中到高。
此外，飓风“艾达”登陆路易斯安那州十天后，美国墨西哥湾的天然气供应大部分仍处于中断状态。
根据安全与环境执法局（BSEE）的数据，截至周二，墨西哥湾天然气总产量的77.89%继续中断。
上周的EIA天然气储存报告也显示市场持续紧张。EIA上周四报告称，储存的工作气体比前一周净增加200亿立方英尺。虽然由于飓风“艾达”的破坏，贸易商已经做好了向仓库注入少量资金的准备，但这低于预期的250亿立方英尺的增加量。
截至上周，美国天然气库存为28710亿立方英尺，比去年同期减少5790亿立方英尺，比五年期平均水平30930亿立方英尺低2220亿立方英尺。
即使最大的天然气生产盆地阿巴拉契亚在2021年上半年实现了自2008年开始在马塞卢斯和尤蒂卡页岩地层生产天然气以来的最高平均产量，但美国天然气价格甚至在飓风“艾达”破坏之前就一直在飙升。
价格上涨的原因是美国通过管道和液化天然气货物的天然气出口激增，这两种天然气今年创下了历史新高。炎热的夏季热浪和低天然气库存也在过去几个月推高了天然气价格。

U.S. Natural Gas Prices Jump 8% align="justify"> After settling 3% lower align="justify"> As of 10:28 a.m. EDT align="justify"> Models for the second half of September predict warm weather with high temperatures, which is expected to drive demand for natural gas.
This week, national demand will be low across the northern U.S. but moderate to high across the western and southern U.S., according to the September 7-13 model from NatGasWeather.com.
In addition, natural gas supply from the U.S. Gulf of Mexico remains mostly shut-in ten days after Hurricane Ida made landfall in Louisiana.
According to data from the Bureau of Safety and Environmental Enforcement (BSEE), as of Tuesday, 77.89 percent of the total Gulf of Mexico natural gas production continued to be shut-in.
Last week’s EIA natural gas storage report also signaled continued tightness in the market. The EIA reported last Thursday a net increase of 20 Bcf in working gas in storage from the previous week. This was lower than the expected 25 Bcf storage build, although traders had prepared for a small injection into storage due to the disruptions from Hurricane Ida.
As of last week, stocks of U.S. natural gas were 579 Bcf less than last year at this time and 222 Bcf below the five-year average of 3,093 Bcf. At 2,871 Bcf, total working gas is within the five-year historical range.
U.S. natural gas prices had been soaring even before the disruption from Hurricane Ida, even though the biggest gas-producing basin, Appalachia, saw in the first half of 2021 its highest average output since natural gas production in the Marcellus and Utica shale formations started in 2008.
Prices were driven by surging U.S. gas exports via pipelines and liquefied natural gas (LNG) cargoes, which have been setting all-time high records this year. Scorching summer heatwaves and low natural gas inventories have also pushed natural gas prices higher over the past few months.
