Abstract: The new-type reverse coupling unit CO1300F-3/25 is developed in the efforts to meet the demand for development of new-type drilling rig. It uses the long-stroke engine for power and is matched with YOTFJ875FLsh reverse coupler. Characterized for large power, the coupling unit is reliable in operation and works together with the series of F-1600 large-power mud pumps. This paper briefs about the structural indexes, characteristics, advantages and key technologies of this unit as well as wide application in drilling services at oilfields. The coupling unit is skid-mounted and easy for installation and movement for field application in different oilfields.
