On February 11, 2025, at the beginning of the Chinese New Year in the Year of the Snake, the registration and filing of the pressure vessels for the compressor units of the Yi206 platform and Ning209H18 platform in the Changning shale gas block of Southwest Oil and Gas Field were successfully completed, marking the start of the company's Southwest Oil and Gas Field boosting and development project and winning a "good start" for market development and capacity release in the new year. The successful completion of this registration and filing not only demonstrates the company's core strength of "strong technology foundation and efficient management", but also consolidates the efforts of all employees with the victory of the first battle of the new year, demonstrating the high spirited atmosphere of "sprinting at the beginning of the year and striving for excellence at the beginning".

 As a key core equipment for shale gas pressurized extraction, the safety and compliance of the pressure vessel of the compressor unit directly affect production efficiency and operational safety. To ensure the stable operation of compressors on the Yi 206 platform and Ning 209H18 platform, the company has established a special working group, strictly following the national "Special Equipment Safety Law" and industry technical specifications, to conduct full process testing, data verification, and filing declaration of pressure vessels. Through the collaborative efforts of multiple departments, a total of 6 pressure vessels from both platforms have passed the registration and filing review of the local market supervision and management bureau in one go. The safety performance and technical indicators of the equipment have fully met the standards, laying a solid safety foundation for the subsequent production of the pressurized mining system.

 With the registration and filing of pressure vessels for compressor units, the boosting development project of Changning shale gas block in Southwest Oil and Gas Field will accelerate. At the same time, the registration and filing results also provide "hard support" for the company to explore the shale gas equipment and technical service market. By demonstrating high standard and standardized equipment management capabilities, the company further consolidates its competitive advantage in the shale gas development field in Southwest China.

In 2025, the company will continue to adhere to the development concept of "innovation driven, quality-oriented", continuously improve its technological level and management capabilities, lead the "annual red" with a "good start", and contribute greater strength to the development of national oil and gas fields!
