Skid mounted drilling rig – dongrui Drilling Rig
What Is a Truck mounted workover rig?
The Truck Mounted Workover Rig is a highly integrated. Self-propelled mobile powerhouse designed for the most demanding oil and gas environments. It combines power, transmission, drawworks, mast, and hydraulic control systems onto a heavy-duty chassis, providing an efficient “all-in-one” solution for well maintenance, major workovers, and shallow drilling operations. well workover ,oil testing,fishing and pump check operations.

The products conform to GB/T23505-2017《Petroleum dirlling and workover rigs》.API 4F 《Specification for Driling and Well Servicing Structures 》.API 8C《Drilling and Production Hoisting Equipment》 and related standard.And have obtained the certificate of authority to use APl monogram.

dongrui manufacture full series of ruck mounted diling. And workover rig from XJ150 to XJ1200,advantages are strong power and good off-road performance. Can work in the condition of -45’℃ to +55 ℃, now many rigs are working smoothly in the oilfields of domestic and overseas.
