德州極端冬季天氣導(dǎo)致天然氣凈提取量猛增10.6%

　　據(jù)油價網(wǎng)2021年4月16日休斯敦報道，美國能源信息署(EIA)4月16日表示，由于2月份的冬季風(fēng)暴，今年采暖季節(jié)的天然氣凈提取量比5年平均水平高出了10.6%。

　　在2020/2021年冬季采暖季節(jié)的頭幾個月，氣溫比正常情況要溫和，但2月份的寒流導(dǎo)致天然氣采暖需求創(chuàng)紀錄，同時由于井口凍結(jié)，減少了美國的天然氣產(chǎn)量。

　　EIA表示，結(jié)果是，截至2021年3月31日，美國本土48個州(傳統(tǒng)采暖季節(jié)結(jié)束時)庫存的天然氣總量為17780億立方英尺，比采暖季節(jié)結(jié)束時的五年平均水平低了1.4%。

　　在冬季暴風(fēng)雪期間，德克薩斯州的天然氣產(chǎn)量下降了45%，主要原因是冰凍天氣。2月17日，德克薩斯州和美國中部大部分地區(qū)的干天然氣產(chǎn)量下降了21%，最低為697億立方英尺/天。

　　與此同時，就在德州凍結(jié)之前，美國通過管道出口了創(chuàng)紀錄數(shù)量的液化天然氣(LNG)和天然氣，這也導(dǎo)致了在產(chǎn)量低迷和供暖需求創(chuàng)紀錄的情況下，更多的天然氣被從儲庫中提取。

　　2月份的極端冬季天氣導(dǎo)致了美國有史以來第二大天然氣需求量的飆升。

　　EIA表示，美國本土48個州2月份天然氣的月凈使用量總計為7780億立方英尺，這是自2011年以來2月份天然氣的最大使用量。今年2月，天然氣儲庫的凈使用量占供暖季節(jié)天然氣儲庫總使用量的37%，而此前5個供暖季節(jié)的這一比例為24%。根據(jù)EIA的數(shù)據(jù)，在2月19日結(jié)束的一周內(nèi)，包括德克薩斯州在內(nèi)的美國中南部地區(qū)的天然氣提取量達到了創(chuàng)紀錄的1560億立方英尺。

　　Texas Freeze Led To 10.6% Higher Natural Gas Withdrawals

　　Due to the winter storms in February, net natural gas withdrawals from storage this heating season exceeded the five-year average by 10.6 percent, the Energy Information Administration (EIA) said on Friday.

　　The first few months of the 2020/2021 winter heating seasons saw milder temperatures than normal, but the cold snap in February resulted in record demand for heating, while wellheads froze and reduced natural gas production in the United States.

　　As a result, working natural gas in storage in the Lower 48 states as of March 31, 2021—the traditional end of the heating season—totaled 1,778 billion cubic feet (Bcf), which was 1.4 percent less than the five-year average for the end of the heating season, EIA said.

　　During the winter storms, natural gas production in Texas collapsed by 45 percent, primarily due to freeze-offs. Total U.S. dry natural gas production during the Freeze in Texas and much of the central part of the United States declined by 21 percent, to as low as 69.7 Bcf/d on February 17.

　　At the same time, just before the Texas Freeze, America was exporting record volumes of liquefied natural gas (LNG) and gas via pipelines, which also contributed to more withdrawals from storage amid low production and record demand for heating.

　　The extreme winter weather in February resulted in the second-largest natural gas withdrawal ever as demand spiked.

　　Monthly net withdrawals of natural gas in the Lower 48 states in February totaled 778 Bcf, which the largest amount of natural gas withdrawn during February since 2011, the EIA said. Net withdrawals in February accounted for 37 percent of all withdrawals from natural gas storage during the heating season, compared with 24 percent during the previous five heating seasons. A record amount of natural gas, 156 Bcf, was withdrawn during the week of February 19 in the South Central region, which includes Texas, according to EIA data.
