·Rational whole structure, high containerization, effectively reduce the frequency of transport. ·The emission meets China 4 or China 5 standard. It is environmental friendly. ·The derrick has front open and is one-section FC mast-type derrick. It raises, stretches out and draws back by hydraulic pressure. Air cylinder lock is adopted. ·The master rotor brake adopts link mechanism remote control in the driller operation room. The hydraulic auxiliary unit is equipped to reduce the work intensity of driller. · Adopt pull rod design to alleviate waggle after dismounting the derrick. · Adopt long-span flexible jack to improve stability of workover treatment when there’s no guy line. ·Dual-engine is optional. The mounting engine can use China 3 standard engine. ·Adopt machine-power- hydraulic-gas integration technology to realize machine automation. Thus, the well repair efficiency and safety can be greatly enhanced, and workers’ work intensity can be reduced. ·Uphold “people first” design concept. Intensify safety protection and detection measures. |
