December 24, 2022 – Huangjia Nitrogen Injection Construction Project


On December 24, 2022, Sichuan Host Oil and Gas Technology Co., Ltd. received an urgent notification from the Chengdu Natural Gas Chemical Plant, requiring the completion of the nitrogen displacement task for the Huangjia Project by 6:00 PM on December 25. Despite the sudden nature of the assignment and challenging weather conditions—where temperatures plummeted from 17°C to -2°C—the company swiftly mobilized one pump truck, one engineering pickup truck, and its construction team, arriving at the site at 5:00 PM, one hour ahead of schedule. The team successfully navigated the complexities of nighttime road occupation and extreme cold, meticulously setting up warning signs along the way. From 10:52 PM to 8:05 AM the following morning, they carried out the precise nitrogen injection in two distinct phases. Throughout the operation, all equipment functioned smoothly, ensuring zero accidents or safety issues even under harsh weather conditions and highly complex circumstances, showcasing the company’s exceptional ability to respond effectively to emergencies.
