今天（21日）0时，位于新疆南部的塔里木油田年油气产量达到3003.12万吨，成为我国油气上产重要战略接替区。\n

\n\n

\n 　　位于大北博孜气区的大北902井近日喷出高产气流，今年这里试油的6口井均获40万立方米以上高产。目前，天山南麓还有60多部钻机正在钻进，近两年，塔里木油田超过100口气井获高产，新建天然气产能90亿立方米。

　　中石油塔里木油田公司总经理 杨学文：“十三五”期间，塔里木油田大力提升勘探开发力度，已经落实两个万亿方大气区，形成10亿吨级大油气区，为新一轮的油气增储上产奠定了坚实的资源基础。

\n\n

\n 　　56万平方公里的塔里木盆地是我国陆上最大的含油气盆地，盆地遍布大漠戈壁，油气大多蕴藏在超过6000米的地宫深处，面临超深、超高温、超高压等极限考验，是世界级勘探禁区。油田的科技工作者攻克了一系列世界级难题，探明油气储量26.7亿吨。
