Zigong City and Natural Gas

With abundant storage, Zigong city has the longest history of large-scale natural gas exploration and utilization. The natural gas utilization in ancient China was originally associated with the salt well. 1700 years age people started to use the natural gas, which was discovered along the salt mine exploration, to cook and boil salt. 1000 years ago, the people of Zigong made a large-scale exploration of the natural gas in superficial layer, which made this area one of the earliest gas field in the world. Similarly, the urban bus of Zigong and Chongqing has adopted natural gas to replace the liquid fuels in 1950s and 1960s. The predecessor of Zigong Tongde Machinery Manufacturing Co., Ltd. made the first compressor in China which is still on operation, the city is gradually developed into a manufacturing center of CNG station equipments.
