中国西部四大气区之一——川渝盆地川渝天然气发现最早、利用时间最长。四川盆地是我国第1口千米气井诞生的地方,是世界第1个规模开发气田建成的地方和最早掌握小口径深井钻探技术的地区。不仅是我国发现天然气田最多(气田气藏逾300个)和产气层数最多(逾20个)的地区,还是第1个产量过100×108m3的气区,也是天然气市场化最高的地区。 One of the four major gas regions in western China - Sichuan-Chongqing Basin, Sichuan Province, the earliest discovery of natural gas, the longest use of time. Sichuan Basin is the birthplace of the first kilometer gas well in China. It is the first large-scale developed gas field in the world and the earliest to grasp the small-bore deep well drilling technology. It is not only the area with the most natural gas fields in China (more than 300 gas fields) and the most gas producing layers (more than 20 areas), but also the first gas-producing area with a capacity of 100 × 108 m3. It is also the most marketized natural gas market in China.
