Shale-Oil Associated Gas: Fourteen Chinese Compressor Trains Enter Service at the Gulong Central Station
Fourteen self-developed compressor trains in four frame sizes have passed their 72-hour running test and entered service at the Gulong shale-oil central processing station in Daqing, where the gas system handles 2.6 million cubic metres a day.
Lead
Fourteen compressor trains developed by the Chengdu compressor branch (成都压缩机分公司) have completed a 72-hour running test and entered formal service at the central processing station of the Gulong shale-oil Q9-layer capacity project at Daqing Oilfield, the company reported.
Facts
The station. The Gulong central processing station combines crude dehydration, light-hydrocarbon recovery and natural-gas processing, and its gas system is rated at 2.6 million cubic metres a day; the station is described as the core supporting facility for scaled development of the Gulong continental shale-oil national demonstration zone. (Source: the company's account, carried by industry media, 2026-09-20.)
The machines. Fourteen trains in four frame types — DTY2000, DTY1800, DTY500 and DTY450 — handle associated-gas processing and oil-and-gas boosting duty at the station, with the fleet mix arranged to cover the differing process requirements. (Source: the same.)
The CCUS connection. The company's account states that the trains' reliable operation supports carbon capture and enhanced-oil-recovery utilisation at the demonstration zone. (Source: the same.)
The industry record. The commissioning was carried in the China General Machinery Industry Association's weekly industry review for the week of 14–21 September 2026. (Source: the association's weekly review.)

Note on sourcing. This item reports a manufacturer's account of a commissioning milestone, corroborated by an industry association's weekly review. We record the verifiable layer — the fleet size, the frame types, the test passed and the station's rated capacity. We do not repeat performance claims beyond the figures stated, and we do not rank or recommend suppliers.
What the source does not state
The reports do not state the trains' discharge pressures, shaft powers or efficiencies, the number of trains per frame type, the gas composition or mole-weight range, the contract value, or the measured emissions or reliability figures since start-up.
Update note
This item is a dated record of a publicly reported commissioning. We append corrections rather than rewrite history; corrections are marked Correction with the date.
