6、雨雪，局部地区甚至有大雪。连日来大范围的雨雪天气致华北、两湖、西北和华东地区天然气使用量增长迅速，天然气供需矛盾突出。中国石油天然气集团公司已采取措施努力加大天然气供应量。铁道部也已开始采取防范措施，最大限度减少雨雪天气对铁路运输的影响。据中央气象台最新天气预报：未来三天，受东移冷空气影响，新疆西部、青藏高原东部、西北地区东南部、内蒙古东北部、黑龙江西北部、湖北大部、江淮大部等地有小到中雪(雨)或雨夹雪，其中，青海东南部、川西高原西北部的局部地区有大雪；贵州中西部等地有冻雨；江南大部、广西北部、海南东部以及西南大部等地有小到中雨或阵雨。中石油有关负责人十八日表示，目前华北、两湖、西北和华东四大
7、气区已联网运行。受雨雪天气影响，华北地区巨大的用气增幅给整个管网运行带来巨大困难，也影响到其他地区用气。目前华北地下储气库已提前严重超采，预计十一月超采气量达一点七亿立方米，将给冬季天然气销售保供带来巨大风险。中石油的数字显示，十一月一日至十六日，华北地区天然气日均用量同比增长百分之五十六。其他几大气区用气量也有明显增长。两湖地区日均用气量虽与计划持平，但同比增长百分之二十二。目前中石油在上游增加供应的同时，大部分管道的日均输量已达设计最大输量，管网达到满负荷运行状态。中石油还通过适当压减其他地区和工业、发电用气，保证北京等重点地区和居民用气。据介绍，中石油已采取应急保障措施，动用储气库来满足
8、需求。同时将控制高峰用气量，优先确保城市居民用气。包含在城市管网范围内的工业用气和发电用气要做好充分准备，参与高峰用气调峰，调减用气量或使用替代燃料，不与居民生活用气抢气，实现天然气安全平稳供应。 10,需求旺盛,A.

The measure has helped mend the deficit of some 680,000 cubic meters of natural gas in supply, but still leaving a gap of 40,000 cubic meters in daily demand, said Xu Jin, director with the energy resources department of Wuhan Municipal Development and Reform Commission.
