Sinopec Machinery’s Third Machine Division is a specialized manufacturer that engages in the research, development, production, sales, and after-sales service of natural gas equipment such as reciprocating natural gas compressors, mobile on-vehicle compressors, and gas drilling pressure boosters. It is the only enterprise within Sinopec dedicated to the manufacturing and provision of natural gas compressor services, and in 2003 it was established as Sinopec’s base for the domestic production of compressors. It originated as the Dushanzi Machinery Factory of the Xinjiang Petroleum Administration, established in 1950. In 1969 it was relocated from Xinjiang to Longweishan in Tianmen County, Hubei Province, and was renamed the Third Machinery Factory of the Jianghan Petroleum Administration; it was one of the five major machinery factories under the former China National Petroleum and Natural Gas Corporation. In 2005, the Third Machinery Factory was relocated to the Wujiashan Taiwanese Investors’ Development Zone in Dongxihu District, Wuhan, and it is now a **-level airport-based economic and technological development zone. The company entered the compressor industry in 1982, and in 1988 it introduced RDS compressor manufacturing technology from abroad through a combination of technology and trade. Research on compressor control and simulation analysis has been carried out in collaboration with companies such as GE, Xi’an Jiaotong University, Huazhong University of Science and Technology, and Yangtze University. Efforts have been made to develop key manufacturing technologies for compressors, which has led to the expansion of the RDS compressor series. Products such as RDSA, RDSB, as well as standard CNG refueling station models, sub-stations, and FB-type products have been developed, resulting in a total of nine series and forty different model types. Compressor products cover all aspects of natural gas extraction, transportation, storage, and utilization. In recent years, with the support of the **Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the group company, various compressor-related projects have been carried out (such as the development of key equipment and tools for deep shale gas extraction, the localization of compressors for the Wen96 gas reservoir, and the development of high-power reciprocating compressors for marine use). These efforts have further enhanced development capabilities, and key technologies in the field of compressors have been developed, including high-speed compressor design technology, integrated control and remote diagnosis technology, compressor design technology suitable for use in environments with sulfur or under oil-free lubrication conditions, compressor design technology without fixed connections, module design and system integration technology, compressor performance testing technology, and noise and vibration control technology. Participated in the development of the standard for reciprocating compressors used in the petroleum, chemical, and natural gas industries, and took charge of formulating the standard SY/T6991 for reciprocating compressors used in oil and gas field vehicles. The 4RDS-3/WKL7042GSI natural gas compression unit won the second prize for scientific and technological progress at the group company level, while the domestic development project of the 4RDSA-2/1500 compressor for use in natural gas applications received the third prize for scientific and technological progress at the same level. The key new product, the 2D4-3/3-250 type compressed natural gas vehicle refueling station equipment, has obtained a **-level new product certificate. The compressor production facility features a large island-style assembly line, capable of producing 50 large compressors and 150 small and medium-sized compressors per year. To date, Sanji Machinery Branch is the manufacturer in China that produces the largest number of reciprocating natural gas series compressors. It is mainly used in the markets of Sinopec, CNPC, CNOOC, as well as local users, and is suitable for both terrestrial and marine environments. It features a low failure rate, minimal vibration, smooth operation, and the ability to function under complex operating conditions. The first domestically produced compressor for underground gas storage was put into industrial use at the Zhongwen 96 gas storage facility in 2012, with its technical specifications reaching international standards. Exporting compressors for FPSOs in Lake Kivu, Rwanda, to enter the offshore market. Six large-scale compressor units have been applied to the Tayu pressure boosting project of Sinopec North China Branch, with a driving power of 3000kW. Domestically produced BOG compressors are used at CNOOC’s Tianjin floating LNG terminal reception station. The first set of pressurization systems, powered by compressors, has been operating continuously and stably at Station 49 in Fuling. Sulfur-resistant compressors provide a solution for pressurizing acidic gases, and they are used in the Tarim Gas Field of China National Petroleum Corporation; the maximum operating time for each such compressor exceeds 10,000 hours, which has led to the establishment of enterprise standards for the design and manufacturing of sulfur-resistant compressors. The gas injection oil production compressor is used for gas injection oil production in the Wen88 and Wen72 areas of the Zhongyuan Oilfield; it operates without a foundation, and its maximum exhaust pressure reaches 35 MPa. An integrated device for gas recovery during testing and production is used in gas fields such as Diniudi and Fuling; an invention patent has been obtained for high-speed gas compressors, as well as a utility model patent for the gas recovery system used in testing and production. The 1250 kW units at China National Petroleum Corporation’s Tuhua Oilfield have been in operation for nearly 20 years. Sinopec Machinery’s Third Machine Division will follow the development strategy of \"core technology + key manufacturing + integrated services\" to refine compressor units and strengthen system integration. While continuing to meet the needs related to the development and utilization of natural gas in oil and gas fields, it will also expand its activities into areas such as refining and offshore industries, providing integrated compressor services for upstream and downstream sectors. The goal is to become a internationally renowned and domestically top-tier professional enterprise in the manufacturing and service of natural gas compressors.

In recent years, as the pressure in the gas reservoirs of the Puguang gas field has gradually decreased, the production pressure in some gas wells has approached or even fallen below the pressure in the transportation network, forcing these wells to be shut down. In order to address the challenges related to maintaining stable production, extend the period of stable production during gas field development, and improve recovery rates, with strong support from the headquarters, the Puguang Branch of Zhongyuan Oilfield Company carried out research on \"wet gas pressurization technology for high-sulfur gas fields\" as well as efforts to develop domestic acid gas compressors. It also initiated the construction of a pilot project for pressurizing acidic wet gas in the Puguang gas field; this project serves as an important means to implement the seven-year action plan aimed at enhancing oil and gas exploration and development activities, as well as to ensure the continuous operation of oilfield enterprises. Since the project began construction, the project team has operated efficiently, concentrating its resources to leverage the advantages of integrated design, procurement, construction, and equipment deployment. By enhancing communication and coordination, they have shortened the time required for the acid gas compressor system to be installed and put into operation, ensuring that it can meet the needs of enhanced production in the gas field in the future
