The project is located in Wanyuan City and Xuanhan County of Dazhou City. The Tieshanpo gas field is the highest sulfur content integrated gas field in China so far, and it is also the first self operated ultra-high sulfur gas field developed by PetroChina. The project includes drilling engineering, internal transmission engineering, purification plant engineering, external transmission engineering, and gas field water reinjection engineering. This project is the first to adopt a "permanent and temporary" combined power supply scheme in oil and gas field surface construction projects, reducing deforestation, saving investment costs, and minimizing the impact on local forests and vegetation. It effectively protects green mountains and rivers, achieves balanced development of economic development, industrial construction, and environmental protection, and has received widespread support and praise from local governments and residents.
