随着新疆塔里木大气田的诞生 ,我国西部地区形成了塔里木、柴达木、陕甘宁和川渝 4个国家级的天然气田。塔里木盆地在 1 999年年底共探明了 5座大中型气田 ,累计探明天然气地质储量 41 90亿立方米。陕甘宁探区自1 990年获得重大突破后 ,现已探明天然气地质储量 3340亿立方米 ,? With the birth of the Tarim gas field in Xinjiang, four national natural gas fields, namely Tarim, Qaidam, Shanxi, Gansu, Ningxia and Sichuan, have been formed in the western part of China. At the end of 1999, a total of 5 medium-sized and medium-sized gas fields were discovered in the Tarim Basin. A total of 41.9 billion cubic meters of natural gas reserves were proven.
